The person behind nitter.poast.org, as seen here, has been outed as some reactionary former dev of 4chan: https://accollective.noblogs.org/post/2021/06/18/admin-of-poa-st-anime-graf-mays-revealed-daniel-stevens-of-ontario-canada/ (CW: racial slurs)
He is also the admin of Poast, which is a reactionary instance on the Fediverse, reactionary to the point where even MSM had articles about it.
Needless to say, I'm going to use another Nitter instance (nitter.esmailelbob.xyz) and I would encourage others to do the same. Here's a list of Nitter instances: https://status.d420.de/ in case nitter.esmailelbob.xyz turns out to suck as well.
Edit: Damn, it turns out esmailelbob sucks as well lol
anyone out there willing to help me figure out what special sauce the remaining instances are using? maybe we could build our own instance.
I'm guessing based on prior research that they are farming genuine account tokens somehow but more details would help
