If you as user block an instance that doesn’t really solve the problem, Threads is still federated and getting your stuff, it’s just hidden from you

Is it more rational than only federating once they’ve proven that it’ll be fine? (instead of waiting for them to prove they’re not)

There’s already a tool for moving over the subscriptions: https://github.com/wescode/lemmy_migrate

No way, are you the k_o_t?
