There are 2 phases to being crowd source banned at Surly Horns now.
Step 1: you get to purgatory at -100 rep. You lose all posting privileges everywhere else
Step 2: permanent banination at -200 rep.
Once you are in purgatory you cannot see rep you receive and from whom, you also cannot give rep. If you start a topic that gets you the good will of community saving you then you can rejoin. If you are still a piece of shit you can get fucked and be gone.
