Realized I posted my account name when doing this the first time, oops.
My account got permanently banned yesterday and I can only assume it was as collateral damage in some ban wave going on.
I guess I shouldn't speculate on that sort of stuff though.
My character's name is Iserys and the only thing I had been doing was participating in a rep raid in Silithus, which had been going on for quite some time. I was grinding for elemental earth for a while before this raid started so when the ban came in I had probably been in the zone, grinding away, for about 2.5 hours, maybe 3.
(edit: I also play on the PvP server, if that knowledge helps in any way)
Never experienced my account being compromised (never lost any items or gold out of nowhere, never disconnected or found myself somewhere other than I logged out) so that is why I would like to appeal.
