I have participated in the hobby for many years. I never used a burner phone. Just gave my cell number. I never had a problem. On the other hand I never frequented backpage girls or STG girls. Only reputable Eccie or Eros girls. And I have seen AMP girls, who do not require any personal info.
I have prepaid for sessions for a few providers I knew well, given them a loan occasionally and never had been scammed or short changed.
Basically I find the providers I have seen regularly to be very honest and really great girls.I fully understand their screening requirements to stay safe.
Reputable providers will not try to blackmail clients. They know that is a much more severe crime than being a provider.
