There have been reports of abuse of the very liberal team-switch functionality available on uber1337.
This has led to a trial currently running on server #3 where this feature has been removed – meaning CS:GO is running as ‘usual’ with the current number of team changes.
Consequently, the anti-AFK settings have also been changed; that is, the system now kicks you rather than moving you to spectator mode.
If this works better in practice, it will be rolled out across all servers.
