Founder of Rexxfield, Michael Roberts

Licensed Private Investigator, and said to be the world’s first professional Internet troll hunter.

Michael Roberts had better reason than most to dedicate his professional life to catching cyber predators – he was once a victim. Previously coordinating white-hat security education for the US Air Force, NATO, the UN to name a few, Michael now uses his skills for private and law enforcement clients. He’s helped all manner of people from school children to celebrities and CEOs. His record time for identifying a troll was 17 minutes in a case where an Attorney General in the US had already spent $100,000 of tax-payers money and five internal attorneys in futile attempts to identify a rogue Tweeter.
