Rotten neighbors and criminals

I just found a webpage called rottenneighbor.com, where you can blame your neighbors for beeing noisy, disturbing or whatever. They also included sexual offenders in this map. Image this map for Phnom Penh: Nearly every house would be marked as either rotten or offending. Ok, ironically speaking. But it would never educate people to stop doing things like being noisy or rape, instead, some would be proud to be on the map.
Sad.
