He basically tried to join a group trying to bring transparency, evidence, and ethics to inter instance moderation to prevent unfounded block list abuse and accusations, its called the UFoI https://UFoI.org
As a result the people who are most guilty of this very abuse added him to a block list even after he left the UFoI... according to him 33 instances blocked him.
The irony is this is the **exact** situation the UFoI is trying to prevent, yet somehow he is mad at QOTO, for this.. go figure.
I do feel bad for him though, its a shame.
