People that can't scumhunt say "scummy" when they know they're guessing, or as just as an excuse to fos someone. It's mainly a tool to suppress rational thought.
Instead of just spamming "scummy" define what you mean. Don't accept people using "scummy" as reason, make them define what they meant. If you've bandwagoned a lynch because someone said "scummy", you're a sheep and you need to stop letting people guess for you. This applies to self voting, but that a separate topic.
Don't be scared to be wrong, if you don't act on your convictions, how will ever affirm them?
