Most drama you’ll see on Fediverse will involve leadership, moderators, and power-users within the following groups who don’t like each other:

Anarchist faction: db0, quokk, nexus, etc

Tankie faction: .ml, Leningrad, hexbear, etc

Liberal faction: status quo enforcers .world, the biggest instance unfortunately. Feddit, etc.

Powertripping/insane mods and admins. A modicum of online power goes to people’s heads here same as anywhere. Stick around long enough you’ll pick up on the repeat offenders via osmosis even if you don’t actively dig up dirt.

Manipulative narrative control obsessed web and app developers. Lemmy and Piefed both have awful people as lead developers. Then there was Tesserect which… recent drama. I’m not getting into it unasked.

Good news is you picked a good home instance with .zip as far as I know.
