@ricmac It will be interesting to see how Threads ventures into the Fediverse. I have no Threads account, nor anticipate making one, so, I cannot really test things or see if, for example, my profile on my instance is accessible or not.
I wonder if Threads will ever really permit open, bi-directional federation with the Fediverse considering moderation concerns within a centralized platform such as their own. It could be that Meta only permits open federation with a few larger Mastodon instances and otherwise blocks out the wider Fediverse, either via purposeful intention or through ignorant naivety adopting Mastodon's #fediblock lists (either would deliver essentially the same end-result). @evan
