Hi all,
To avoid or at least limit repetitive spambot attacks, I'd suggest implementing the following technical restrictions on the site:
1) A user can post external links only one day after their fifth post on the forum. Exceptions can be made for popular harmless sites like YouTube or Wikimedia projects.
2) A user with less than 50 posts cannot make more than five posts with external links per hour.
If this cannot be implemented technically (of course, I don't know how exactly the engine works), we can at least discuss more effective available ways to prevent mass spam.
Any opinions or ideas?
