I would like to know boe the championship’s moderator can throw out another player Who is not following the rules.
There is only one way in which users can be kicked out of the league by the league moderator and that is if user goes inactive for 72hours.
So it's not possible to kick managers out of the league unless they are inactive
For issues like this, you can only ask the manager nicely to follow the rules you guys have set for your league and hopes he complies else nothing can be done about it. But if he is breaking OSM rules then yout can report him through our system by going to the managers profile and use the report cheater tool you find there.
