title: do you need captcha validation in newsletter subscription?
body: <p>I am using a custom captcha php script along with news letter scripts to let users subscribe using an email id. The method of registration is based on jQuery.post command.</p>
  
  <p>My question is that am I really safe If I remove the captcha validation from my subscription script. The subscription is simple. For example</p>
  
  <pre><code>mydomain/subscribe.php?email=myemail@somedomian.com
  </code></pre>
  
  <p>The subscribe.php is called along with email as parameter using jQuery.post command. I am new to web programming stuff and don't have much idea about spammers in conjunction with above scenario. Any advise would greatly be appreciated.</p>
  
  <p>Thanks</p>
