This particular discussion is a rather meta conundrum, at least to me.
When most forums discourage litigating thread moderation outside of designated spaces, discussing this is effectively litigating some other forum's in-thread moderation.
I'm not aware of a reference or general theory of moderation, where theory and practice have an analytical framework we can use to productively break things down, without running the risk of the contentiousness of said moderation infecting the thread discussing it (presumably why it's already considered a bad idea discussing moderation in-situ) or it serving as a stalking-horse for the argument the moderation interrupted.
On the other hand, it's their house, and trying to discuss any example is picking apart someone else's business.
Discussing another forum beyond specific data points found there has been an area I've been reluctant to delve into because it drags in complication or sets up a situation where judgement can be passed with no opportunity for rebuttal (or silly argument by proxy in different posts in different sites).
GAF's notoriety and focus on an owner seems to at least meet a level of novelty, but is there a point where the business of the new forum is just that, some other forum's trivial business?
I think the theoretical aspects might be interesting, at least from a more clinically detached perspective--but risky in the sense of clinical analysis in a biohazard lab.
