No it matters... Posting a positive or negative review on rentmen is just a few clicks away, just like a making a mean/bitchy comment on an escort's reputation. Writing a review on daddy’s takes too much of an effort for some folks to actually do it.
I agree with the rest of what you said and I always promote guys with few reviews on RM and on here. Btw there was an old thread about escorts who asked not to be positively reviewed because they want to remain under the radar.
