Are there any other plugins that have been installed?
If there aren't, I think it is just old spammers who already created an account who are able to spam. By the way, Brandon, do you delete the spam users, or just the post/thread?
Other than that, I have noticed that nowadays, very spam threads are going around. Maybe Mr. Martus is getting faster, or the spam plugins are resolving just in time for Christmas, New Years and Kickoff (Thankfully).
Just for the sake of it, I still think that the occasional spam thread is all right if deleted a couple hours later because it allows us to grab a laugh at all the grammer errors they make
