Have hackers infiltrated this game? We have an attacker that was level 12 early this morning, now a couple hours later, he's level 21 and just keeps coming back and attacking us. That's an incredibly short time to climb 9 levels, not to mention the cost of it. He's part of a 97 member clan, 

It's not so hard grow up fast. A few packs with gold and boosts, resources from clansmans = profit.
