As proof of the trouble that the internet can get you into, look no further than Maxi Sopo, who was on the run for credit fraud.

He managed to get himself busted because - get this - he was updating his Facebook profile by telling everyone what a great time he was having and in so doing giving plenty of clues about his whereabouts. Don't today's youth watch spy movies any more? Does he not realise that if you are a wanted criminal then the last thing you should be doing is making public announcements on the web? This is on a par with the woman who went swimming with polar bears (see below); at least she was probably suffering from a mental disturbance of some kind whereas this is really just plain dumb. Enjoy prison, Maxi; you belong there.
