This morning -GMT Time- i read admins controlling some abusive buildings of a player in game chat, so they are working in the problem.
The TC's unused are sadly the last line of defense if u have a "happy trigger" building neighbour, and im sure that the huge build of L6 have only 1 TC. The limitation of the number of TC per player may not solve this problem, i think.
The L6 Twin Towers are called "the 5 FPS area" xD
Sorry for my bad english
