I don’t see anything dodgy about the ad. Looks like a typical Brazilian import that’ll move on fairly soon.
If you check the phone number listed and the images you'll see evidence that this is someone who is touring UK.
The photos associated to the profile seem to be a mish-mash and probably of more than one person.
I'd assume I was going to meet whoever I thought was the least attractive looking person in the photos and make a decision based on that.
I think there are better options out there.
