Something Awful made you pay $10 for an account. Directly to the forum. If you got banned you could pay another $10 to try again. Somehow this didn't lead to that bad incentives even though you'd think it would.
Ban reason and the moderator name were public on Something Awful, which allowed the community to respond (actively or passively), and for more senior moderators/admin to take public action against rogue moderators. The transparent audit trail countered the incentive to ban somewhat, but a lot of people also treating getting banned as a game.
It's because you can't reasonably put everything in the rules. They would be thousands of words and still have holes and special carve-outs, _and_ users will still argue about rules application if you say your rules cover everything.
It's more reasonable to have "a spirit of the law", so to speak.
Lemmy isn't simply Lemmy since it's federated. A screenshot like this is somewhat meaningless without specifying on which instance this happened. There are instances with very lax or even no moderation at all.
For the majority of large, well-federated instances, I don't think it's meaningless, because deletions also propagate to other instances.
If a mod on one server doesn't like something I say, and they delete my comment, all the other (well-behaved) federated instances will also delete my comment.
Of course this also creates problems in the other direction, like servers that ignore deletion requests.
That combined with a large amount of blocked instances across the board, I feel like you get into this "which direction would you like to piss into the wind" situation where you have no idea how many people/instances will actually see your message if at all.
