By the way from other french articles:
For 30 euros, you gave him a phone number, he would give you his bank statements. For 50 euros, he would give you his identity. For 150 euros, driver license number, date of delivery, ID card number, social security number, license plate…. You could even know about the flights he booked.
For 300 euros, could get his entire life. It was possible to get the police documents and those from Interpol. But the most interesting with the 300 euros offer was that with a simple phone number you could get all his phone calls and it's physical location even month before. This was what chocked me the most. There was a higher price for celebrities and politicians : I believe those people have a special status.
