I asked and enough of you answered that allowing to federate with threads.net even for the lolz would be considered too risky for y'all.
So I've gone ahead and added threads.net to our blocklist.
From the sidebar:
… the following subjects are explicitly not allowed …
- Nothing extreme-right-wing. This includes conspiracy theories, SovCit, Pro-Police, AnCaps etc. We’ll know it when I see it, don’t test us!
So I would guess "fash" means fascist content.
