What did that update even do? I thought it would keep those spammers out, or at least a fat majority out.
It's a work in progress and has some shortcomings -- particularly if a mod isn't online. But I guess you had to be there the weekend before registrations were temporarily disabled to get some perspective.
One thing I need to do is ratelimit new topics much harsher than new posts. I'd rather a spammer be forced to make a bunch of posts than a bunch of topics. I'll fiddle with the numbers this weekend but at least the machinery is in place.
