A few years ago, the Lemmy Developers decided to keep their political views on lemmygrad while keeping lemmy.ml more neutral. Now they are banning users who are critical of their actions and bigotry.
Anti-Tankie posts may put you at risk of being banned from commenting and posting on the lemmy.ml instance.
Seeing some of the stuff that’s made it to the front from Hexbear about the Israel situation makes me wonder if people are going to run the risk of promotion of proscribed terrorist groups by hosing federated content from them.
In the US there’s a list terrorist organisations that Hama’s could very well be on. (I’m not up to date on this). And it is, or at least was, illegal to provide material support to those organisations.
In any case it would be very hard to make such a charge stick in the US if all you have is internet postings, no overt acts, and no money changing hands. First amendment and all.
