Survivor Talking Poker

[Talking Poker]

Example: Down to 6 players, my alliance/team/whatever is down to just me and I'm on the ropes. So I leak the password and 4 of my buddies show up and we collude so I win the tourney and get immunity.

This is an extreme example that would be obvious to spot, but surely you can see how ANYONE playing who isn't supposed to be is a problem.

Moreover, what's to prevent my "alliance" from getting on AIM and sharing our hole cards with each other?

The more I think about it, the more I think this might not work.

But I'm glad you are confident.
