I'm sorry I failed to be clear that I wasn't questioning in this specific case, but am referring to general practices that I suggest are good to observe by default. I think we have evidence elsewhere that such practices are needed in public discourse right now.
That said, I understand that this specific case is complicated, iff someone feels intimidated, and iff and there is no authority to whom to appeal, so maybe it's an exception to general best practices.
Okay, I understand now that you were not making that implication. Thanks for cleaning that up.
Since general practices explicitly allow anonymous complaints for whistleblowing, including for anonymous complaints in public fora, I don't see how your appeal to general best practices affects anything - this already is part of general best practices.
Perhaps you could describe what practices you are thinking of?
And, indeed, we are seeing that very prominently in the last few years, in US/world news, as part of a major and unresolved threat.
This general situation is one reason to adopt some practices. Getting practice with practices is good practice.
