It's a scam, mate.
Only doing outcalls, unless she knows you. Cash is fine unless it is an outcall, then she needs a deposit for her security. I can guaran-fucking-tee that she don't know anyone that texts, so its going to be outcall, and it is going to be a deposit and if you're stupid enough to send a deposit, well, a fool and his money are soon parted.
Also, as a rule of thumb, check the views. If a chick has only been viewed a few thousand times or less, be suspicious. Legit providers have tens of thousands of views.
I could be wrong but you aint gonna see me lining up to be the first to TOFTT.
