Just do not discuss about any sexual act for money over the phone or before/during/after the sessions. Most smart escorts won't ask for it. They just assume, you will give it to them at the end. Most customers do discreetly If not, they will get banned, blacklisted or info exposed to others. Also, LE wants you to TALK or do something to demonstrate that you were there to exchange sex for money, since they have to PROVE it to convict.
These days, anyone can steal anyone's information. One can get hacked online. Lost ID, Driver license could be used by others that share same ethnic background. Someone can use other people's phones to call or text others. Also, most iphone are linked to work/personal emails these days. Have you not noticed?
In addition, work or personal emails can be forged. Last time, someone was caught forging other people's emails.
Therefore, nothing can be proven without getting caught or confessing. Of course, when you see the escorts, don't blur out all your personal info, since they can testify against you, if necessary. Lastly, never use credit card or give out SSN; these not only leaves paper trails but also you can become a victim of identity theft
