We have a
dedicated NOA thread with a good rundown and timeline. If you've got some time to kill
Armcha1r did a stream on them a couple months ago, though this was before we found out Sayu might still be working with them again.

ghostarchive.org
I'm like 90% sure this is gaslighting. Later, I'm going to try to see if her post-Shanghai stream is still up somewhere. I know I downloaded it at the time, but I almost certainly have deleted it since then - but I might have it hanging around on a backup somewhere.
