The other problem is that many WGs share, or pass on, profiles. This is really bloody annoying! You view a profile, check the feedback, check the punters who have provided the feedback, and then decide to give it a go (having called the lady of curse). You can even check auto-censored.com etc.
You then find out that the genuine feedback previously provided was for for another girl! It's happening a lot where I live.
So it's tricky, but generally I don't trust feedback.
