I guess my point is that banning people is a very, very extreme case, and while negligence may be ugly, it may not get someone banned.

It may be hard to prove that someone intended to be fraudulent to the point that they should be banned.

The bats would be cheaper and probably more effective. Wave them around, just don't actually use them. Of course, you'll probably just get sued for making someone feel uncomfortable... and yes, the lawyers would go after Louisville Slugger, and maybe the poor bastard who owned the ash forest...
