If she doesn't want it out here I doubt she wants it in the ML...but I know, I know you have that right!
Like others stated...she could have several reasons why! Some guys just like to troll certain ladies reviews and make comments (some neg..some positive) for no reason! Even when they haven't seen them, they may just not like their on board personality! She may have been a target before for whatever reason and doesn't want to go through that again. That can get you some enemies...Yikes, but I don't know nothing about that...lol! Or maybe she doesn't get much clientele here and the review would benefit her more on the other site!
BUT Unless you grab your balls and ask her, you will never know! So yes be a gentlemen, respect her wishes (if you want to see her again) and just recommend her in all those "Who's the best at blah blah threads"!
