In-game hacks wouldn't be a new obstacle for me. Some time ago I had my best defense broken by someone who's attackers were all 2-4* I revenged that team and eliminated all with a single AOE. Not to mention I've once seen players with their player levels in the 20's and 40's in the top 50 or even less so I wouldn't be surprised if some of those lonely people are at it again with their game hacks.

Not only are hacks against the rules, they're also against the spirit of the game. Just takes the fun out of earning your rewards.
