Re: Taking over for friends??
There isn't much they can do to prevent people from sitting around a computer and playing as a group. They are other ways groups can "cheat" online, but I won't get into that here to give anyone ideas.
Even stopping a players friend from signing on from another computer through IP tracking is hard to prevent because what if I play on more than one computer? or if I buy a new computer or move I'll have a new IP address right?
We'll just have to wait for the first poker room to implement webcam technology into the poker software so we can see the actual players playing. |
