Which Massage Places are Legit?

I was driving through the Y at Oak Hill and noticed signs for no less than 3 massage places in a small area. How can I tell which ones are legit and which are what this board considers to be AMPs?

Stop by and try them out. No magic answer.

You should be able to find them here if they are AMPs. Or if you google them and they have a bunch of stock pictures of hot Asian girls they're probably an AMP.

Legit massage places don't put girls on their website or ads... at least none that I've seen.
