It sounds like they’re going to be allowing anti-LGBT hate speech, which was formerly a ban-worthy offense on their platform. Reddit and most Lemmy instances have rules against this, so I imagine Squabblr is going to attract the same sort of people that like using Truth Social.

She’s apparently a MAGA supporter, so I have no sympathy.

Doesn’t Peertube already do this?

The great thing about Lemmy though is that a community you interact with or even moderate doesn’t need to be on your instance. If you’re a member of Beehaw, which doesn’t allow community creation, you could start your Dune community on Lemmy.ml or another instance and moderate it with your Beehaw account.
