On the Rooster Teeth Wik, there is this anonymous user who keeps harassing and insulting other users, and repeatedly uses vulgar. I have blocked him indefinitely a month ago, but he has returned with a different IP in the same range as the old one. I have a feeling he might come back again another time. Does anyone know how to block a certain IP range?
