Blue got 4 containers (on clarion ultimate V5?) and he removed all of them...On the last match ( bathrooms) he removed all the cons too but he got kicked by the other players.(Camilo was on bathrooms) http://i.imgur.com/N8t62gN.jpg

Either show the rules if he appears, or simply give him a short ban with a detailed explanation of the 'remove' rule.
