lots of girls look the same
but here one profile is in Manchester, one in Birmingham, doubt if they are related. But if they are, its the same girl so it doesn't matter does it? But if she proves to be size 16, walk away
your bigger and more likely risk is that the profile is a B&S con, in which case you'll probably get neither of the girls, but someone completely different.
Yes there is a risk, but not the one you imagine
