How to get rid of spam forever?

Are you saying you are getting a lot of ‘people’ signing up to your website?

Here are two ways you could help reduce Spam (Has helped a lot for me):

  1. Keep an eye on your access_log within the server. If you see the same IP addresses accessing your website, block them.
  2. Require sign-ups to have to verify their credentials by clicking on a ‘Confirm’ link that is sent to their email address.

Hope this is a good start in your battle against Spam!
