Spam accounts created automatically [closed]

Question

I need some urgent suggestion. In my live site a lot of spam users are being created every few minutes. I will install captcha and MOLLOM but I need to delete the spam users. How can I identify them and how do I prevent this from happening again?

Please advice

Answer 1

How to prevent it from happening you already know:

• Anti-spam tools like Mollom
• Captcha

For mass deletion, use Views to list them:

• Create a new users view (add new view, show: "Users"),
• add relationships you feel will be helpful to identify spammers, like "User: Content authored".
• add filters based on these relationships, like
  • Created unreasonably high amount of content or no content at all,
  • only users with account younger than the spam wave,
  • et cetera;
• use VBO to actually delete unwanted ones - just check them, or use select all and uncheck good guys. Of course good filters will reduce number of good gu
