Round 2B: Let’s say mastodon.social doesn’t defed from Threads after this first incident. (Assume they’d probably demand a concession from Meta, but maybe it’s a weak countermeasure.) I don’t know if it’s likely, but one can imagine LOTT Threads users start signing up for mastodon.social, and use that as the base for their next attack. I guess at that point mast.soc gets mass fediblocked. So now we’re split, and vulnerable.
