I blocked them on my instance last year. Fuck threads and any instance that goes along with them.
Lemmy.world looks like it will be federating, according to https://fedipact.veganism.social/
That’s precisely why I left L.W. They also were removing community posts voicing opposition to threads federation. I witnessed it firsthand, where posts I commented in (and in which the majority of comments opposed it) were removed.
Now they removed the piracy communities again after promising not to. They are straight up untrustworthy and don’t care about what their users actually want.
I am happy on feddit.de. They are defederated from Threads and the tankie instances.
I’m curious, did you catch the reason listed on the mod log for the removals?
