@Gargron shame Mastodon doesn't allow users to opt-in to #Threads because opt-out is not consent, and blocking an instance is particularly hard.
I tried to find how to do this just using the web UI more than once in the past and gave up.
I think it would be better if users got to choose, which means opt-in.
I also dislike the takes which day, ah lots of people are following x on threads so users obviously want this. That's disingenuous.
