Also dmca just means that the admin has to make a reasonable effort to remove things reported as no compliant. Aka they ban or remove offending posts and they are in the clear.
I’m gonna be honest. And I run my own instance, albeit solo, this content isn’t my concern. It’s the CP/CSAM shit that folks like burggit.moe we’re spreading that got my liability concerns up. The feds go hard on that shit (as they should) and will hold a hosting admin accountable as if they were the ones viewing and reading it.
Dmca is pretty clear cut and toothless. I’ve dealt with it plenty as a network admin. As long as you remove it when notified, you are in the clear. This strikes me as the admins having a political opposition to it and using their made up code of conduct as a reason and when pressed just saying “well liability”.
That said I don’t know where they live and the laws for me may not be the same as someone hosting in Germany, who may go hard on that stuff. So who am I to judge? Just saying dmca isn’t really a concern.
Also they’re hosting provider could just cut them for “abuse” especially if they are already using a lot of resources and if that’s a concern I get it. .
