They (Rheinland players) built a player owned base without any IFF in GMG's claimed space. GMG declared siege. Rheinland players decided to put a Kishiro IFF on this POB, and told GMG to cancel the siege or they will report it to Game Masters (Rule 3.5 Threatening with sanctions). GMG did not cancel the siege as the POB was still built without their approval.
