The wider concept, where they put actuality to the idea that every account on the network is a privilege and if you're a jerk there's a real penalty, I don't think you could do on Lemmy. It's just not the culture here.
I think it would be possible for one community to have a rule that if you pretend someone else said something they clearly didn't say, it's a temp ban. It would be difficult for a certain crop of user accounts to deal with, but I think those are exactly the ones that aren't adding anything but suffering to the conversation, so nothing would be lost by booting them until they learned. I think it would be a good idea. Case in point, this fucking guy. I've given up trying to explain to him that I don't want genocide any more than he claims not to, and I don't even really like Kamala Harris, I just mostly think Trump in charge of the US is a biblical horror, and I want to avoid it. Somehow that keeps turning into that I love Kamala Harris and defend every part of her platform. I don't even know why I've invested so much keyboard time into this conversation, other than the idea of someone promoting don't-vote-ism is really alarming to me, and I want to say something when I see it.
