It is possible to take pictures in Poland, Romania, wherever and then work over here. Ditto if the pictures are on some EE escorting website it doesn't mean they are fake.
Precisely.
The lesson here is if it looks too good to be true then it's probably a fake, good point by the OP about looking beyond the sexy arse, far too many don't look beyond a picture of a gorgeous girl that's why they keep using the B&S scam - I'm not immune myself at times.
Do a reverse image search, there are loads of pictures at the moment copied from facebook, instagram and so on, if you get a hit on these then it's most likely a fake.
Combine this with the profile being unverified, fairly new, highly suspicious fb (or none at all), all services being offered etc and it's a fake. Report to AW and post details on the fakes thread on UKP.
