If you've never read anything on TFL about anyone being kicked *off* TFL it's ptobably because:
- It's a rare occurence (we don't notch our grips each time)
- It's generally by mutual consent
- It's not a matter that should be handled publicly
As far as reasons, there is a Policy Statement that all Members agree to before signing up. Simple document, really. It contains a common sense code of conduct.
Reappearance is most rare, as people are generally responsible and know when they've taken advantage.
