Agreed F.B. and S.N.
Usually when S.P.'s start up a profile,and want to try and drum up business, they want to get a few quick feedbacks
if you look at the alleged punters they will have either 0 or very few previous feedbacks. Likely the S.P. herself or her "manager" has set up a couple of accounts , just to get the ball rolling.
If a reviewer has a good number of F.B. under his belt, especially over a period of time, then i normally accept it as kosher. The main thing is do a bit of research by "drillling back"
