Am I going to be able to tell whether the person/account that I am interacting with is of 'threads' or 'meta' origin?
...McRocker.thread?
...McRocker.meta?
...because I don't want to hang out with facebookers (do not have an account in that platform)
@McRocker Once they turn federation on (AFAIK, they haven't yet) I'm pretty sure that means Threads/Facebook people will have an address that denotes as such.
So something like @person@threads.net, so it should be pretty clear. In Mastodon's settings and some apps, I believe you have the option to block entire instances, so that is an option to you.
