Oh - I should have said “main perpetrator” (i.e. Andy B, who seems to be the main pro-active part of it). I did not mean to deny others are involved, or to say they’re not bad, rather that Andy B seems especially bad from putting so much energy into something so intentionally destructive and malicious.
I guess I don’t fully understand this bit. I’d definitely agree with his actions being tacit endorsement (i.e. being publicly silent on the matter) and instigation (e.g. the lie about no contact requests). But I don’t understand him to have an ongoing active involvement which I infer from “led”. Is there a part that I missed?
