ablack6596: I can only _guess_ what happened to your thread(s). And from what I hear, my guess is this...
Some moderator saw your thread about Tiger already being pirated. This puts the thread in a difficult position, since we _do_ have a board rule about warez, and we generally simply don't allow talking about it. (There's been a LOT of talking in the past about the whys etc., we do _not_ want to over it in this thread again...)
Such threads have the tendency to attract people who are looking for the item talked about, which ends in questions like the bold one in above post (I know that was demonstrational, of course).
So now when a moderator sees such a thread, the thread's in a grey area. We moderators all have our own ideas, and we usually don't blindly delete threads. Some might come across with a longer, others with a shorter leash. That's normal.
However: Once a moderator has decided that a thread has to go according to board rules - and talking about pirated Tiger copies is certainly within the grey area, and a thread about it could go either way... - and put the thread away, that's done. What we _certainly_ don't like is threads like "Why was my thread deleted?". You can ask a moderator in private messages. You can see who's moderating each forum on the forum homepage -
http://macosx.com/forums - and click on a moderator's name. While it could be that you get the wrong mod by doing that, the mods of the forum will talk about the subject and come to a decision - unless it's very clear what happened from the very beginning.
(Posting the nfo probably didn't help the thread either, btw.)
