Here is my basic approach to rooting out fakes, I will customize it as circumstances require:
I was intrigued by this ad too, and even though my now well-honed spider-sense said "fake" I did the due diligence anyway.
Spidey-sense: when she looks TGTBT, shows face, says is available 24/7, claims pics are 100% 1000% or 100000000% real (of course they are real pics, they just aren't really her), wants e-mail transfers, will only accept phone calls (no text or email)
Due diligence: 1) search on the phone# - look for other ads posted under that # with different handles (escort names), different sets of pics, and outside Canada. Lately this has been less productive because the ladies/pimps keep changing #s and using temp local #s
2) search on the handles on CAF and PERB for reviews - not always easy with common names like Ashley, Tiffany
3) Reverse Image Search on Tineye and Google - most productive avenue. Often you will find pics are ripped off from somewhere, were used outside Canada, are found in other ads with different handles, different phone#s and different locations
4) Search on these new phone#s - this often turns up a different set of pics and handles
5) Search on these new pics - even more phone#s and handles turn-up
