John McAfee is such a master of disguise that even though the most elite police unit in Belize has more or less set up camp at his house solely to find him, he's able to wander around close enough to the house to watch their every move simply by dressing up as a German tourist in a Speedo while hollering "Leck mich um ausch!" at passers-by.
This has to be a hoax.
I think another possible explanation is that it is his blog, but with the element of truth carefully dispensed and the element of hyperbole liberally dispensed.
I'm not sure that's more likely than hoax, but it's a possibility I maybe wouldn't eliminate.
