Although I neither have any interest in buying Vod's contact information nor do I have an extra $50k, I don't think this would be a very good investment. Anyone willing to pay this much obviously wants to harass you and once the harassment level reaches a certain point you can simply change your phone number and the information would become worthless.

Although there are probably enough scammers on here that are mad at Vod for foiling their scam attempt that someone could potentially resell his information for less money but to more people that you could theoretically make a profit.
