Yeah, Threads can do all it wants. I've set a preemptive block. I want nothing to do with Threads. Of course, I cannot control what other instances decide to federate and get my content that way. But I won't make it easy for them.
What steps did you take to preemptively block it? I want nothing to do with Threads either but am a bit confused on what I should be doing. Is there a list of instances who defederated from threads or something?
I run my own instance so I simply added a block in the instance configuration. If I had to hazard a guess, I would say the folks at lemmy.world have most likely done the same.
If anything was being blocked you would see it there. AFAIK lemmy.world does not normally block/defederate anyone as a standard policy (including threads.net).
If you want an example on the other end of the spectrum go see https://beehaw.org/instances they are currently at 405 instances being blocked including threads.net.
