If you haven't received a notification it simply means your post wasn't individually reported, and thus removed, but rather the entire thread you were posting in probably got removed/nuked by a moderator..

This usually happens with threads that have an enormous amount of spam / low quality replies.. the posts that got deleted were most likely from either Bitcoin discussion, or Offtopic.
Sucks for you, but sometimes it has to happen, ( due to the enormous amount of account farming that is going on in these kind of topics.)
