Why would you confidently state such a thing to our forum when you have no idea of knowing what is 'silently deleted' on our forum, no way of knowing who deleted it or of knowing the the whole imposed action was simply personally motivated?

Or at least be in a position to see and judge if what you state to be true is the case?
