Everyone, especially those who are new to the industry, please be careful with your personal information when you respond to ads here and elsewhere. These advertisers are all people who want to make money from sex workers, most of them are unknown, and some of them are not nice people. Don't trust them just because they have a website or sound nice/businesslike on the phone. You'll get yourself into trouble that way!
As a rule, don't give anyone who you meet through the sex industry any information that you wouldn't give to any punter that called, or anything that you wouldn't want published. This includes your personal phone number, identifying pictures and address.
If you get to know someone properly or you're dealing with an organisation that has a good track record, you might decide that it's worth trusting them, but don't make this decision lightly and certainly don't just because someone tells you to.
