No, Tom should be encouraged to post here as often as possible. The more unfortunate remarks he would have to explain to a judge in the alternate reality where his lawsuit actually goes through, the funnier.
Think of it this way. It's a public service that this site keeps Tom spinning in his wheel all day. Without this place and AMB, Tom might go outside more. Might meet some dogs and children along the way.
Tom is the kind of guy who walks into a bar, picks a fight, gets dogpiled and force-fed shit, then struts out because he got a free meal out it. I don't know why you'd ban such a wonderful clown.
