He fell into the trap of visiting chat sites and talking to girls, but has now repented
Question

                I fell into the trap of visiting a website on the Net to which I subscribed by paying money. The site initially appeared to be good but most of those who visited it were just playing. But I started to correspond with more than one hundred girls, and I spoke with them on the mobile, and I spoke to them in romantic terms and I met some of them. Now I have repented to Allaah and I hope that you can advise the owner of this site, because it has now become a means of evil and a means of approaching the opposite sex. May Allaah reward you with good.
Praise be to Allah.
    We praise Allaah for having enabled you to repent, and we ask 
    Allaah to make you steadfast in adhering to the truth and the right path. 
    May He guide young Muslim men and women to guard their religious commitment 
    and their honour. 

    You should note that it is not permissible for men to start 
    such websites or to visit them. The owner of this site is one of those who 
    are addressed by the warning in the verse (interpretation of the meaning): 
“Verily, those who like 
    that (the crime of) illegal sexual intercourse should be propagated among 
    those who believe, they will have a painful torment in this world and in the 
    Hereafter”

    [al-Noor 24:19]

    Indeed he is more deserving of this warning, because the 
    warning in this verse was addressed to those who like immorality to be 
    propagated, so how about one who actually works to make that happen and 
    become widespread? 

    This is the way that is known to end in what we see and hear 
    and read about those who use these means to approach the opposite sex. How 
    many men have lost their religious commitment and how many women have lost 
    their honour? Some of them have found no other way but suicide to escape 
    from the dark tunnel that they got into because of corresponding and 
    speaking to non-mahrams. 

    We have already discussed the ruling on corresponding and 
    speaking to non-mahrams. Please see the answers to questions no.
