Craigslist or why no one on the internet knows you're a dog

so I answer an ad from a woman with a daughter who wants lodging in return for services like cleaning, after a bit of back and forth she sends me a whole spiel and a bunch of pictures of her daughter and about 3 or 4 pictures of her mostly around a motorcycle. I do a quick search on her find nothing, do a quick search on the daughter and get hits on a actors website in the UK. Which leads to the question of course is she real or bogus but as yet I can't tell. The only thing I can tell you for sure is that when I mentioned a background check to determine she wasn't a felon  she disappeared faster than water on a griddle.
