Many forums have this game. The game has many names. Here's how it works:
In the beginning of a season, I send a PM to one person, they are called the poacher. I will send another PM to another random player.
Each round, a poacher sends me a PM of a participant. Then, the ranger sends a PM of who he thinks is the poacher is. If it is the right person, I will tell the ranger he/she is correct. If not, I say no. Then, I will announce who was poached. He is OUT for the whole season. Then the normal participants have to dsicuss who they think is the poacher. If they decide on a person, that person is also OUT. This can repeat till the poacher is found or everybody is dead.
