I joined today to play in the tourney and these other players that were there were staying in Do Not Disturb so that they could manipulate the standings. When they are in Do not disturb no one can challenge them per the rules so the program didn't pit them against anyone except who they wanted when they were in the lobby. This is totally UNFAIR play. Please review this and disqualify them. Complete unsportsmanlike conduct and they knew it.They were even laughing about it as we were pitted against each other while they stayed where they were. Hope this gets reviewed.
