Ourk, it sounds like from that first thread that the money you gave to him for his mount had nothing to do with the ban. I'd imagine if it did have anything to do with the ban, you'd have got caught up in it as well (since you were the one giving him the gold), which it doesn't sound like you did. It's very good of you to try and help though (and very generous with the gold!).
Good luck leveling a new character (or moving on from the game) Ihadasword.
