I'm seeing alt accounts of people who truly deserve to be banned getting banned, and their account doesn't last too long. Also, I notice that many users (Especially in the Off-Topic) that used to be dicks and often went for personal attacks and insults have either completely stopped, get banned or warned, or they have lowered the amount of those personal attacks and insults considerably, and when they do end up having a fit of rage, the post gets met with a warning, or justice, or whatever. The CoC is a leash, or a harness, whichever suits your view. Is it bad? No, it was necessary, since users that experienced the "Freedom" of "No Rules" abused their privileges to the point of no return, and even escalated it to offsite insulting (In rare cases). For me, it seems to restrain the community from going too far off the deep end, and it's doing its job. Good for the community to know when going too far is really going too far.
