We got this kind of Yahoo! booter stuff from time to time but this one is worse and Yahoo! should patch it immediately.
Your opponent just boots you DURING THE GAME from the table and room. When you log back to room you’ll see that you lost that game and points. I don’t think that we can detect if our opponents has this booter before the game start . I suggest you don’t play with strangers for a while and you may join to a pool league cause they won’t have this kind of players in their leagues after someone use it one time.
Let Yahoo! know about this so they can find a solution immediately .
