@Peter Koy - Facebook - FBI??
"Is that proven?"
Yep, 100% verified!
"They only have my fake details..."
Makes no difference, if you are using the same keyboard entering fake and real data, even on different websites: Every keyboard writes letters with a unique 'signature', and thus FaceBook International/FBI can match fake and real details.
Wrapping more than. 4 inches/10 cm of the the cord of the keyboard in tinfoil blocks the unique signature of the keyboard.
If you are using a wireless keyboard (or mouse) only a tinfoil hat helps.
