Several people here use it as a resource. Including myself.
Never tried the integration part. So i don't know how feasible it is to hack it in.
The last time I looked into it there were some plugins for specific forums but not ubb.
I just look up suspicious ones and manually ban them for a certain period of time.
I am a little leery of a permanent ban per ip since they constantly change so a ip might be a bad person for a while then it is not after a few months.
