I just got kicked out of a game of pool by what I thought was being disconnected. I then tried to re-enter and it said "youve been barred until tomorrow" etc. I don't even talk to people unless they talk to me, and nothing bad is ever said...nor do I cheat so I'm confused.
You probably double-clicked the button as you were trying to join the table to play and when that happens you get "barred" by Yahoo.
This issue has been reported to Yahoo on many occasions over the years by league owners / moderators and has yet to be resolved !! The ban may vary from 3 mins to several hours. You did nothing wrong per say just be careful when you join tables. Click once and let it load. If it does not load leave from the game room (not the table) and then come back in the game room and rejoin the table again.
