Let's continue. How to protect yourself?
First of all, of course, to visit girls with a good reputation. I don't mind advising you girls whom I know personally. Some girls are very jealous of their customers. As for me, I don't see the point: you know that I meet other men, I know that you meet other girls. If we have something special, you will comeback, right? If not, you will find someone else anyway. You can't match everyone's taste. Sometimes we (girls) ask each other to check a client in one's list. And situations like: 'Oh, why did you put him in your personal blacklist? He is my favorite client,'- happen pretty often. Like an escort can have a lot of positive reviews, but for you she will be 'nothing special'. So I think there is no reason for me to be greedy for recommending you some of my colleagues, as you shouldn't hesitate to recommend my company to your friend .
To protect yourself use another sim-card and another phone. It's almost impossible to buy a pre-paid sim in Norway without ID, but you can fill up an application to hide your personal information, so no one can google your number and find out your name and address. And, of course, don't use this number wherever else: in Facebook, LinkedIn, twitter etc. It's not the best advice according my own interests, of course: I prefer to know something about the person whom I'm going to meet, and if I can't find anything in google, you should be very convincing when we talk on the phone,- but it will protect your privacy.
One more thing. It's better to use Viber, WhatsApp, Skype or e-mail for communication: it's much easier to get a list of your phone calls and SMS, then this chats. And always delete all messages, and ask the girl to do the same (honestly, I keep letters in my e-mail, but it protected with double passwords). I delete everything from my phone, because I realize that I can lose it someday or somebody can steal it. It's pity to clean the memory sometimes: some of messages are so nice, that I wanna keep them forever, but I choose safety.
Another advice: don't send any explicit messages, like 'Baby, I feel so horny!' or 'What services do you provide? I'm interested in OWO.' It's better to stay finally without OWO, then without reputation, isn't it?
So, just be like James Bond and play a spy-game, then nobody will have a chance to blackmail you. And remember: if you let somebody blackmail you once, he will never stop. Don't let it happen.
