Actually, anybody can see
the list of reported items. If your threads are being reported by another user, that may explain the moderators actions.
As a first step, I would try talking to the mod who deleted your threads. TBH, I always PM someone if I delete one of their threads so they know why it was done, and what not to do in future.
But... as El Jamié says, if you feel in any way "victimised"; or just aren't getting anywhere negotiating with a particular moderator, speak to one of their superiors. They should be able to mediate.
As for MentaL closing threads in "Account Support", is your account locked? Is it hijacked? Hacked? No? It's probably not an appropriate place for such a thread then.

Sadly, MentaL doesn't often have time to respond to people in person to explain that sort of thing. If you re-posted, you're lucky he didn't action it though. The rules state that if a thread is closed by a member of staff you should not try to re-start it in a fresh thread.
