Are you disputing that the FAQ page tries to rank your site higher by having autogenerated answers to questions your site is not authoritative on? Are any of the questions on the FAQ actually written or meant to be read by a human?

Either way, if you want to keep a positive image going, don't take internet comments personally. Just incorporate the feedback and make changes if you feel it's warranted.

It might suggest that your perspectives and priorities are still wonky.

I would prioritize immediately and permanently removing the material and the practice, over posting questionable whataboutism arguments vs. spam.
