It seems you should be able to block the IP address@Josh :
This a.m. there were 164 threads posted by wawibek417, and they just joined yesterday. There are also five threads by acc0untcreste22, who just joined today. When they post a new thread it's easy to get rid of them, but sometimes they post in an existing thread. This means we have to read every thread to make sure we find them. I got rid of wawibek before I did any research on them, so I can't tell you where they're from, etc. but acc0untcreste22 is from the Netherlands.
