We are looking into recent forums spam. We have located the IP address and looking into a solution. Some of the ideas proposed by Neel are:
- Do not allow duplicate title
- Do not allow numbers and special characters in a title
- Restrict user to a single question every few hrs or so
- Once a user is deleted or deactivated, remove all of his forum posts and article comments.
- Look for suspicious words and block them
- Remove Captcha. That doesn't help much.
- English language only
- Limit amount of lines unless it is code format
Any more ideas?
