As I said, the primary thing about the idea is the added risk of a permanent ban (both sides).
Update: All of those have been banned yesterday already.
I all for it Lauda.
I think members should also be able to see who is and is not banned, past, present and future.
It is hard, or a waste of time, to investigate/report/watch when we do not know if an account is already banned.
Maybe mark their profile page? This should be easy to achieve?
