My statement refers to this claim: "I'm 99% sure this is written by an LLM."

The hypocrisy and entitlement mentality that prevails in this discussion is disgusting. My recommendation to the fellow below that he should write a book himself (instead of complaining) was even flagged, demonstrating once again the abuse of this feature to suppress other, completely legitimate opinions.

I'm guessing it was flagged because it came off as snark. I've gone ahead and vouched it but of course I can't guarantee it won't get flagged again. To be frank this comment is probably also going to get flagged for the strong language you're using. I don't think either are abusive uses of flagging.

Additionally please note that I neither complained not expressed an entitlement. The author owes me as much as I owe them (nothing beyond respect and courtesy). I'm just as entitled to express a criticism as they are to publish a book. I suppose you could characterize my criticism as complaints, but I don't see what purpose that really serves other than to turn up the rhetorical temperature.
