I think it's pretty silly to attach much significance to the "town" displayed regarding collusion. Are you going to be afraid of collusion if two players from New York City are on the same table? Los Angeles? Chicago? London? Springfield?

Furthermore, on most sites, you can type anything you want into this field. If two people are going to collude, don't you think one or both of them might lie about were they're from? Besides, with instant messaging, cell phones, etc. two players don't have to be in the same country to collude, let alone the same town. If you're concerned about collusion (and it's someting you should look out for, but not be paranoid about), watch the way people play. If the same two players are in a hand togeter a lot, and raising back and forth, especially if one ends up folding before the river, they might be colluding (or they might both be maniacs). If they are doing this nearly every hand, just trying to buy pots, they may be colluding, but are doing it so stupidly that they reperesent a significant money-making opportunity. If they are doing it only when one of them has a good hand, get out and report them.
