The app won't get you in trouble as it is geared also for dating sites like Match.com from what I read on research before I downloaded it myself. That is why I like it but haven't used it yet and have not been charged.
Heck it is even reviewed by Forbes magazine for dating sites all you say is you are on Match.com and don't want to give your info out to meet a crazy. If the guy has other well known providers vouching for him there you can contact them as well.
Plus being an escort is not illegal people pay for your time
