The reason cited by the mods is misinformation. Not supporting violence, or any other reason. Saying that Luigi isn’t the shooter is considered misinformation and trolling.
In America, the law is innocent until proven guilty. But on lemmy.world, the rule is guilty until proven innocent, and anyone saying the accused is innocent is a troll.
The law part was about their complaint about glorifying violence (see some of his past stuff he complained about, though I think the last one I checked he deleted).
