Suddenly Meta can see a much wider social graph for me. They can find any alt accounts. They can recommend those to the people I know on Threads / Instagram / Facebook -- or to complete strangers.
If those strangers hate me or people like me, oh great, now I'm facing all kinds of new harassment from this poorly moderated meganetwork.
(Obviously many people in marginalized communities have already explained this to us all. All credit where it's due, I'm just walking through the mechanisms here)
