You know, for a small amount of bitcoin, people might be willing to get DOX's on themselves, just to know what could be found by determined searching about them online. Might be a viable business idea!
I would be willing to do this for people for a small payment. You have to understand that all information about a person can be found given the skills. No matter how paranoid someone is about concealing their information, they have and will make mistakes. IP addresses, cookies, MINTM, phishing, grammar analysis, activity, 'friends', pseudonyms etc can all be leaked very easily with even one small mistake made years ago. A full dox from any one of these information's can reveal fullz of any identity. It's very interesting.
PM me if you want me to search you and tell you how I found your information.
