i thought we had something going on,mangago...

i used to be quite active on the question section; i would reply, ask questions and share things. And during that time never ONCE, not ONCE did mangago erase any of my questions or answers. Time goes on, and for no reason in particular i stop participating in the forum section. When i got back i saw that mangago had made an eliminating spree of most of my answers and questions. Why are you so cruel mangago?! What did i do to deserve all my words to be erased? What is the reason? Or does mangago randomly select answers to be erased?
