Never been done? Let's dust of a recent story from Overwatch. Back at launch, you had an option that was called "Avoid this player". It did exactly what you think it did. It removed them from the matchmaking for you. You'd never be matched with or against them. So there was that really good Widowmaker (sniper character) on Japan(?) server. So good, people used that feature against him because he was too good and he destroyed everyone. He couldn't find matches for hours/days because people got salty.

Moral of the story, you may want a system for good reasons but people will abuse it and you may end up on the receiving end for something other than it's intended purpose.
