First reviews that go against "perceived wisdom" can get quite a hostile reception. When I first joined I decided not to post a review of my positive encounter with an SP who had received mainly negatives on here, particularly as certain established members were quite vocal in their opinions of her.
But being asked for additional info is not being hit on. There is some basic info that should be included in any review, such as location, cost, basic description of the SP, etc. (AW profiles get recycled). If you don't know about certain services because they are not your thing, then all you have to do is say when asked.
