First, posts are deleted for all types of different reasons. The vast majority of posts are kept, you must have posted something that was either useless/pointless to the thread, or was baiting/insulting.
Second, to answer your "question" in the other thread, your "calling out mods" thread wasn't deleted by "phag mods", it was moved to Smacktalk, where the worthless threads go.
