While instances will be the correct place to check it, it appears that, at least while Threads don't have federation enabled, blocking it does not show up on that list.
meta (threads) will not support fediverse already. They said they will do in some later version. So for the completely practical part, you don't need to do anything right now.
Isn't threads a Twitter clone? Will it even effect Lemmy? For me personally I don't use Mastodon, but I might if threads is successful. I use Twitter to follow famous people I like. If famous people move to the fediverse because of threads that will only make sites like Mastodon better in my opinion.
My understanding is that Mastadon and Lemmy are both federated and I’ve seen Mastadon posts in my Lemmy feed somehow so it’s not unreasonable to assume threads could eventually populate its way over here at some point.
Well, if you're on desktop and you don't mind installing scripts on your browser, there's a Tampermonkey/Greasemonkey script. https://lemmy.dbzer0.com/post/141704
Second this. After the Reddit fiasco, I also deleted my Meta account and everything having to do with it. I want absolutely nothing to do with them or listen if they died as a platform or not.
It's easy and painless to create a new account with a different instance, so if the instance you're on isn't doing what you want, just delete that account and switch to a better instance.
You can definitely create a new account elsewhere, but I'm going to need a 2 click solution to export my presence on my current instance and to import it into the new one before it's "painless" or "easy".
I don't care about my comments or posts, but the block lists and subscriptions need to travel.
