i got some suspicion on 2 players, and i think that they're multi-accounts, but there is no way of reporting them outside the game, how could i report them to an admin?
This player may have been reactivated in October 27th 2017
KDM, either report them in-game by clicking on the "i" button next to their name on the diplomacy big board, and then select "report this player" (drop-down menu includes "multi-account"), or contact your favorite game operator directly through the COW email system (under the "Messages" tab on the COW main page). I used to use the in-game "bug" report button, but that's apparently not the right way to do it.
If you suspect a multi account, click diplomacy, then the i to the right of the user name. That should show a 'report player' option.In the report window change the drop down to select "multi account".In the description, please include all suspects and everything you can that makes you suspect multi-accounts.
