I signed up on a site to find out about live home-games and now I get emails from strangers about wanting to work together in micro to make profit. It's sad and all, but you know that many people out there do this.
On
Poker.com my friend was playing and these two guys were talking and one of them said to follow the other. My friend sneaked into the open table and eavesdropped on their chat. They were working together, but at a low-limit open table. This was only in $1/2, but he picked them off for a good amount. They still do it and they're on his buddy list. Justice prevails.
