But that's a pretty serious escalation.
Consider this scenario:
Alice: This code is retarded.
Bob: Mod action! Two day ban for saying a slur.
Alice: Lol no.
That's pretty trivial, but how do you escalate from there to mass resignation with none of the fight leaking?
So, nothing has dropped yet, so let's have some speculation.
I know very little about the people involved, so these speculations are structural.
