The foreign spambots are now using AI to get past the "registration question" I have, which used to be too tough for them.
They are easy to spot, so one potential solution is simply requiring validation before a new user can post.
The downside is that real users will have to wait before they post, and many people don't want to do that. New users with an interest in this site like to just register and participate right away.
With that said, we are a small group, and don't get that many new users which aren't bots.
What do you guys think?
