As I once posted in DV, it obviously serves as a police fly-trap. Police catch bread-stealers and petty drug dealers (stupid criminals), not pension-stealers and the big-time legal drug pushers, ie pharmaceudical companies (smart criminals).
DV does have some use. I've found it helpful for my own data-mining purposes. DV has confirmed to me that some borderline retards do manage to utilize the internet in rudimentary ways. Some of the stuff written is priceless, especially the mud-flinging sloganeering of rigid-minded ditto-heads.
