I have been to Joy on several occasions and trust me she does not care about your information once you give it to her.
She will not use it to blackmail you or "ruin your life". It is strictly for her safety to make sure you're not an asshole, molester, rapist, etc.
Give her what she asks for, set a time show up on time, pay her fee and you will be left with a feeling of "JOY" you will return again and again.
