They are a major rip off.
They scoop up info from women's ads and posts them without permission. Sometimes it is just outdated info, sometimes they swipe photos of one woman and put it on another's profile. Often the "reviews" are copied along with other info, but sometimes they just make up reviews.
Rumors (this part I cannot confirm, the rest I know with certainty) is they hire a few people to crank out random reviews.
