They're annoying. 108 post in 1 day is sad. People come and post in old topics and it's a pain. I mean what could we do to stop them.
If the posts are LQ you can PM a staff member, I've done it in the past and they've taken care of it. As for posting in old threads I'm pretty sure bumping old threads is against the rules.
I think Omni should make it where they have to have at least 1 week registered and no more then like 30 Post perday if they are LQ.
