Although there isn't an exact definition of what ratholing really stands for, many players consider it an unethical act. This is because it cuts down the chances of recovering the money players have lost previously if the winning player leaves the table and then join in again, only this time with a lower stack. Whatever the reason for players to decide leaving the table, a "complex" solution to the issue was layed out to the players who assisted Pokerstars at the Isle of Man meeting in a Business Requirement Document (BRD), stating that what needs to be done is identify the players presumed of ratholing and estimate their stack sizes when they leave the game and then implement minimum buy-ins when they join the table again.
