He looks for bad sites to send them to the centre which will block them. Is this good or bad?
Question

                I was searching the web hunting down the unethical sites and sind them to king abdulaziz city of sciences and technology to block them not to be seen . is this work for me or against me as a moslem ?.
Praise be to Allah.
      This brother is to be commended for his protective jealousy 
      regarding haraam things and for his hatred of sin and desire to combat it 
      and rid the people of its evils. But we do not advise him to look for bad 
      sites in order to tell the centre to block them. That is for many reasons, 
      including the following: 

    1 – the Prophet  (peace and blessings of Allaah be upon 
    him) has informed us of and warned us against the temptation (fitnah) of 
    women. Undoubtedly the fitnah of naked women in different poses is very 
    great. 

    It was narrated that Usaamah ibn Zayd (may Allaah be pleased 
    with him) said: The Messenger of Allaah  (peace and blessings of Allaah 
    be upon him) said: “I have not left behind me any fitnah that is more 
    harmful to men than women.” Narrated by al-Bukhaari, 4808; Muslim, 2740. 

    2 – The Muslim is commanded to keep away from places of 
    fitnah and to flee from places where it is present and shun its people. 
    Undoubtedly seeking out these sites goes against all of that. 

    It was narrated that ‘Imraan ibn Husayn (may Allaah be 
    pleased with him) said: The Messenger of Allaah  (peace and blessings of 
    Allaah be upon him) said: “Whoever hears of the Dajjaal, let him flee from 
    him, for by Allaah, a man may come to him thinking that he is a believer, 
    then follow him because of the specious arguments that he presents.” 
    Narrated by Abu Dawood, 4319; classed as saheeh by al-Albaani in Saheeh 
    al-Jaami’, 6301. 

    Ibn al-Jawzi (may Allaah have mercy on him) said: 
Beware – may Allaah have 
    mercy on you – of exposing yourself to the causes of calamity, for it is 
    unlikely that those who approach fitnah will be safe from it. Just as 
    caution leads to being safe, so too exposing oneself to fitnah leads to 
    doom, and it is rare that one remains safe from fitnah when approaching it; 
    even those who are safe from fitnah when they approach it will not be safe 
    from thinking about it or being influenced by it. 

    Dhamm al-Hawa, p. 126 

    3– The Muslim is commanded to lower his gaze and avoid 
    looking at haraam things; checking on these permissive websites and what is 
    in them goes against this command. 

    Allaah says (interpretation of the meaning): 

    “Tell the believing men to lower their gaze (from looking 
    at forbidden things), and protect their private parts (from illegal sexual 
    acts). That is purer for them. Verily, Allaah is All‑Aware of what they do”

    [al-Noor 24:30]

    Ibn Katheer (may Allaah have mercy on him) said: 

    This is a command from Allaah to His believing slaves to 
    lower their gaze and avoid looking at that which is forbidden to them, so 
    they should not look at anything except that which Allaah has permitted them 
    to look at. If their gaze happens to fall upon something haraam, then it is 
    unanimously agreed (among the scholars) that if a person’s gaze falls upon 
    something haraam unintentionally, then he should look away immediately. It 
    was narrated by Muslim in his Saheeh that Jareer ibn ‘Abd-Allaah 
    al-Bajali (may Allaah be pleased with him) said: I asked the Prophet  
    (peace and blessings of Allaah be upon him) about an accidental glance, and 
    he told me to look away. 

    Tafseer Ibn Katheer, 3/282 
4 -  The saheeh text 
    states that it is forbidden for a man to look at the ‘awrah of another man, 
    so what about a man looking at the ‘awrah of a woman? 

    It was narrated from Abu Sa’eed al-Khudri that the Messenger 
    of Allaah  (peace and blessings of Allaah be upon him) said: “No man 
    should look at the ‘awrah of another man, and no woman should look at the 
    ‘awrah of another woman.” 

    Narrated by Muslim, 338. 

    5 – The Muslim is forgiven the first glance, but repeatedly 
    looking at corrupt sites goes against that. 

    It was narrated that Buraydah ibn al-Husayb said: The 
    Messenger of Allaah  (peace and blessings of Allaah be upon him) said to 
    ‘Ali: “O ‘Ali, do not follow one glance with another; you are forgiven the 
    first but not the second.” Narrated by al-Tirmidhi, 2777; Abu Dawood, 2149. 
    classed as hasan by Shaykh al-Albaani in Saheeh al-Targheeb, 1903. 

    It was narrated that Jareer ibn ‘Abd-Allaah said: I asked the 
    Messenger of Allaah  (peace and blessings of Allaah be upon him) about 
    an accidental glance, and he told me to look away. Narrated by Muslim, 
    2159. 

    Al-Nawawi said: 

    What is meant by an accidental glace is if one's gaze falls 
    upon a non-mahram woman accidentally; there is no sin in that initially, but 
    he must look away immediately. If he looks away immediately, there is no sin 
    on him, but if he persists in looking, then he has sinned, because of this 
    hadeeth, for the Prophet  (peace and blessings of Allaah be upon him) 
    commanded him to look away. And Allaah says (interpretation of the 
    meaning): 

    “Tell the believing men to lower their gaze (from looking 
    at forbidden things), and protect their private parts (from illegal sexual 
    acts)…”

    [al-Noor 24:30]
    Men must lower their gaze and avoid looking at women at all times, except 
    for sound and legitimate purposes, namely testimony, medical treatment, 
    proposing marriage, buying a slave girl, buying and selling, etc. In these 
    cases it is permitted to look only as much as is necessary and no more. And 
    Allaah knows best. 

    Sharh Muslim, 14/139 

    6 – The Prophet  (peace and blessings of Allaah be upon 
    him) called a forbidden glance the “adultery of the eye”. In addition to it 
    being haraam in the sense of transgressing the limits with regard to 
    looking, it is also an act of ingratitude for the gift of sight that Allaah 
    has bestowed upon the Muslim. 

    It was narrated from Abu Hurayrah that the Prophet  
    (peace and blessings of Allaah be upon him) said: “Allaah has decreed for 
    the son of Adam his share of zina (adultery), which will inevitably happen. 
    The zina of the eyes is looking, the zina of the tongue is speaking; the 
    heart hopes and wishes for that and the private parts confirm it or deny 
    it.” Narrated by al-Bukhaari, 5899; Muslim, 2657. 

    Al-Nawawi said: 

    What this hadeeth means is that a share of zina is decreed 
    for the son of Adam; in some cases zina will be in a real sense, namely 
    unlawful sexual relations; in other cases it will be zina in a metaphorical 
    sense, by looking at haraam things, or listening to stories of zina and 
    things that have to do with it, or by touching a non-mahram woman with his 
    hand or kissing her, or by walking to zina, or looking, or touching, or 
    speaking in haraam ways with a non-mahram woman, and so on, or by thinking 
    of it in one’s heart. All these are metaphorical kinds of zina. 
“The private parts 
    confirm that or deny it” means, zina with the private parts may or may not 
    take place even though a person may have been approaching that. And Allaah 
    knows best. 

    Sharh Muslim, 16/206 

    7 – There are an estimated 8 billion permissive websites, up 
    from approximately half a billion in 1998. So how about now? If you were to 
    give each website a quick glance, how would your heart end up? How much time 
    would you waste in seeking them out? Undoubtedly doing that would destroy 
    one's heart and body, and would be a waste of time. 

    8 – Continually looking at these evil and provocative sites 
    may cause one to become attached to them, so his heart would be filled with 
    forbidden love and become corrupted. Thus he will have exposed himself to 
    fitnah and doom after having been sound and healthy. 

    Ibn al-Jawzi (may Allaah have mercy on him) said: 
A person may be exposed 
    to the causes of love so he falls in love, and he may see a person and this 
    first glance does not create love, but repeatedly looking at that person and 
    mixing with him or her may lead to what was unthinkable. Some people may 
    look at a person and that creates some kind of love, but then they keep away 
    and the love disappears, because continual looking may cause love to grow, 
    like a garden planted with seeds which, if it is neglected, will shrivel and 
    die, but if it is watered it will flourish. 

    Dhamm al-Hawa, p. 237 

    Ibn al-Qayyim (may Allaah have mercy on him) said: 
The more looks follow 
    one another, the more the heart becomes attached, like water with which a 
    tree is irrigated. If too much water is given the tree is damaged. Similarly 
    if glances are repeated that undoubtedly corrupts the heart. If the heart is 
    exposed to this problem, it will turn away from what it has been commanded 
    and the person will be faced with problems which will inevitably lead him to 
    commit forbidden actions, and his heart will be destroyed. The reason for 
    that is that the one who looks enjoys looking the first time, then he wants 
    to look again, like eating delicious food, when he takes the first bite. But 
    if he had lowered his gaze from the outset, his heart would be at peace. 

    Rawdat al-Muhibbeen, p. 94, 95 

    And he said: 

    Letting one's gaze wander leads to becoming heedless about 
    Allaah and the Hereafter, and will make him intoxicated with love, as Allaah 
    says concerning the lovers of images (interpretation of the meaning): 
“Verily, by your life (O Muhammad), in their 
    wild intoxication, they were wandering blindly”

    [al-Hijr 15:72]

    Looking is like a glass of wine, and love is the intoxication 
    that results from that. The drunkenness of love is worse than the 
    drunkenness caused by wine, for the drunkenness caused by wine will pass, 
    but the drunkenness of love rarely passes until one is in the throes of 
    death. 

    Rawdat al-Muhibbeen, p. 104 
9 – Repeatedly looking 
    at those evil sites may lead a person to commit haraam actions, or to 
    imitate the things he sees. So it starts with looking, and ends with 
    committing haraam deeds. 

    Ibn al-Qayyim said: 

    Looking is the origin of most of the problems that befall 
    man, because looking generates thoughts, then thoughts generate ideas, and 
    ideas generate desires, and desires generate will, which then becomes 
    stronger and becomes firm resolve, in which case the deed will inevitably be 
    done unless there is something to prevent it. Hence it was said that 
    patience in lowering the gaze is easier than patience in bearing the pain 
    that comes afterwards. 

    Al-Jawaab al-Kaafi, p. 106 

    10 – Repeatedly looking at those evil sites causes other 
    kinds of harm too, such as desensitization, and after a while you will never 
    regard that thing as evil and you will get used to looking. This is a sign 
    that the heart has died and lost the shar’i sensitivity towards sin. Another 
    effect is that you expose yourself to suspicion, if someone sees you going 
    to these sites or if others see that on your computer.  

    Finally, 

    What you should keep away from is looking at these sites, 
    even if the purpose is to inform the authorities of them, for the Shayatan 
    may make you go to these sites on this basis and then lead you to worse sins 
    after that. 

    There are technical means available which mean that the 
    Muslims does not need to seek out these sites, and there are specialized 
    committees in some government departments and companies who block these 
    sites. Undoubtedly when a committee in a work place views such things, that 
    is not like a person viewing these sites alone at home, because the person 
    who is doing that alone is more likely to fall into the trap of these sites. 
     

    We are not speaking of something imaginary or something that 
    is impossible or unlikely. We often hear stories of righteous young men who 
    have been tempted by these sites; they start with a glance, then they waste 
    their time with them. 

    You have no need of all that; protect your capital and do not 
    take risks. We ask Allaah to write your reward in full and to make you 
    steadfast in adhering to truth and guidance. 

    And Allaah knows best.
