Possible reason why not being attacked
Here is an idea guys. A large number of the current clashers are not very good at strong attacks. They haven't found the right troop combination that would be cost effective and thus make wrong army compositions. These people, apparently realized that they were either building too strong armies and could not get enough loot from the opponents resources or were building too weak troops and thus didn't manage to break enough collectors from the opponents. Either way they were losing resources. So possibly they realized that they were making more resources by just not attacking and collecting what ever their boosted resources would give them. Maybe this is the reason. When the boost is removed, then they will probably start attacking again.
