All of a sudden, my post count got diminished by 64 posts this morning

I didn't receive any notification that my posts got deleted, which you usually receive when just your post is deleted by a moderator. Obviously, the whole thread was trashed. Since my recent posts are all in place (I checked my post history), it is some old thread that got deleted, likely created years ago. I don't know which thread got deleted, I don't know who deleted it, I don't even know if I'm somehow involved in that but I do think this is not a good idea at all since this possibility allows easy abuse by moderators if they decide to start a personal vendetta against a certain user by deleting old threads with his posts. I don't think that I was a victim of this vendetta (if there is any), and I hope that I will never be but the issue is certainly present and it finally revealed itself. So my proposal to the forum administration is to disable deletion of old threads (say, older than a few days) by moderators unless given explicit consent by Theymos. Really, if the thread didn't get deleted at once (within a few days), it pretty much means that it is worth staying here, while deleting an old thread feels like a spit in the face of the posters
