This has been my experience. I have known a lot of actual professional historians and they tend to be super nice people. Mods in that place are far too edgy and absolutist to be real historians.

Several of the users make their IRL identity publicly known. I don’t know if any of the mods do (that would be brave), but I don’t think they’d be reeling in content from tenured academics for a decade if it was all a sham.
