I presume I have had a social ban, at the conclusion of a trial I was no longer able to whisper, trade, mail etc, even through I was perfectly able to do all of those things in the previous trial.

Frustratingly, I was unable to trade a well sort after piece of equipment I had looted with another player.
I have looked at several threads on this issue, and I note that a reason is rarely given, but I really would like to know if this is something I have inadvertently done (so I don't do it again) or if it is a bug.
