Perhaps the OP is misstating some data (not facts) inasmuch as
the predilection of many "Hobbyists" to cast aspersions on their fellow "Members" ( 
he said members )..., for their taste in paid entertainment.?
Not to cast aspersions, but to me "many" means a lot and for the most part I regard most of the adverse commenters are rather very few in actual numbers compared to the hundreds if not thousands of folks resident here.
That said, a few thoughts:
Yes, it would seem that more than a handful of commenters have forgotten their own former "newbiness" and are harsh instead of kind when commenting on reviews or on reviewers' choices, both on the provider, the providers' rates and/or services, etc.
I rarely comment on reviews in public (or, for that matter, in private tags) unless the review iseither very outstanding (to me) or severely deficient or insufficient or very questionable. But I may often send the reviewer a PM or some links to help improve his future reportage.
Yes, ladies are not permitted to post in review threads, and, yes, they may post in the coed -- but imo 99 pct of the ladies are intimidated to do so and thus just take their lumps or leave it to folks who really know them (WKs or not) to rebut a review.
Few of us very often consider the reality of the hobby -- in that providers and hobbyists are true
PARTNERS IN THIS ENTERPRISE
-- although seems to me that the providers more often than not get the short end of the stick on the boards.
