The /r/InterestingAsFuck mod, /u/ibleeedorange, says this [1]:
>I really don't know every sub he was banned from and if/what he did, but from looking at his post history he seemed to have just posted his QQ in a bunch of subs which then got him banned because he broke rules there, then he harassed mods and posted misleading comments like the ones I had to remove in IAF.
It's worth noting that /u/ibleeedorange is a high-profile user, but does not moderate the same subreddits as those mentioned in the OP.
It's not only the user who was banned from a broad range of subs, the mass deletion of comments (which from reading them on ceddit are not objectionable) is additionally egregious.
I haven't even started referencing the pretty inarguable range of referenced personal accounts of behaviour of these mods.
There's a point at which the idea of this being emergent and unproblematic is still plausible. We appear to be beyond that point.
