A few have. But when it happens people just start frequenting alternative communities. The good karma flows like water through the easiest path. So when an admin or a mod says they find the term bro offensive, people just unsub and find a better community.

Wouldn’t really matter in a federated network like this. Mods banned you from a community? Make a new one. Account banned? Move to another instance.

There’s zero reason to feel attached to online accounts like these, which is the only thing you can lose on Lemmy.
