REALLY NICE! Just installed to my vBulletin 3.8.5 and looks like a real winner. However...
I was thinking that leaving the User name check enabled would be a problem as I suspected that common user names would get flagged. For instance, if someone tries to use "Fred" they should get flagged according to
http://www.stopforumspam.com/api?username=Fred. I tried testing this by registering a new user with the name Fred and it was allowed even though I have User name checking enabled and the above URL suggests that it should have been blocked. So maybe I'm not understanding how this works...
