I agree with most of your points, and they should definitely look into getting more active moderators on their instance.

But I’m not sure I understand what you mean by safety?
They took less than 2 days, but the way you word it sounds like someone was going to die because the ‘content’ was up for more than 24 hours?

Idk, this whole thing just feels like an over-exaggerated response to something that could have been handled with a simple report.
