Kurton (a.k.a. Bajo Hazard on Facebook), the guy who creates proxies and in general tries to ruin the game, is now a member of the Facebook KDice group. So now he can see who's a member. So if you have any identifying information here, he can find you there.

And maybe he'll make a fake profile of an attractive women and then add you as a friend to get more information. If that sounds a bit outlandish, keep in mind that Kurton has made hundreds of proxies here, so we're not talking about some normal guy.
