The problem is anybody can go in and re-edit the Wiki articles at any time. So after doing proper research and a nice compilation of an article that maybe took weeks to do, a 14 year old playing "Mafia Wars" on SP3 can come in and mess it up using only his imagination as reference. Yuck!
A decent writer/investigator's worst nightmare. Imo, they should lock the most important organized crime pages so that those anonymous shit kids can nog longer add their own fantasies.
