Last evening there was one. I banned it because I just logged on, and then they immediately made a new account and started posting. I banned that one as well, and then they made another new account, which I also banned, and then they gave up, I guess. What's the point of the spam, though? Since they don't have any links in the posts, I assume it's for SEO hacking or something.
Adding an hour wait to the post would be ideal @brad also emailed confirmation for registered users. Or we can implement something RPF did where mods have to approve people who signed up based on them answering a question like "Why did you register on this forum?" @ThinPicking
