I am certain nobody will agree with my opinion, but I will share it anyway.
This sounds to me like a design problem. If you don't want to risk someone expressing an opinion, then give them a drop down of things they can choose from to say. "zug zug" "LokTar O'Gar!"
If you want a social platform where people can express opinions, then keep that thing distanced far away from anything where money, competition, politics, etc... are involved. People will do what people can do. In this circumstance, humans were set up for failure and they will fail again. Keep the social platform identifiable names away from names used in a competition.
