From my observations, threads sometimes get moved if they are posted in the wrong place. I am sure if you post something totally out of line, it will be deleted. If a thread is going down hill (turning into fighting and insults), the thread is locked, but not deleted. There are also some things that the regulars will not tolerate, and will state their opinions to the point that the original poster deletes his post. These are things like secret feeding, etc.
