mods had unilateral control over their communities until very recently. short of doing anything illegal or breaking TOS, mods could ban whoever they wanted for any reason. what stopped this was the fact that communities would riot if mods were to ban random users they simply didn’t like. look at places like /r/latestagecapitalism, /r/blackpeopletwitter, /r/witchesvepatriarchy, or /r/conservative, they will all aggressively ban users or block users from posting if they do not go through verification or disagree with the group think. and the community loves it because they’re stuck in their echo chambers.
