I think this is a dumb idea. We're not leftists, we don't need a hugbox. If you're worried about losing arguments to NPCs don't be. Without being able to censor you they will just go back to reddit and cry about it. As for actual paid shills, they will just copy and paste as @Khro_ said. The best way to deal with shills is just be on the lookout for glowy behavior and bad faith, anti-White argumentation.
