Seeing as you brought the fact that the post was reported by you into the public domain, these are exactly the kind of reports that we generally don't act on. We are not the taste police. What you find offensive, is largely irrelevant I'm afraid. Our job is to act on reports that may have potential legal consequences, and as much as you would like to think so, poor taste isn't in that class.
Over half the reports we get are people complaining about other people saying things that they consider to be offensive. Our own personal view and moral compass doesn't come into it, and sometimes we might agree, but we're not going to do anything about it. It's just a waste of our time quite honestly.
Good to know the report button is essentially pointless then.
