I had not read the "in-game rules" before but it is exactly the following point which is described :

"2.2. Breaking the game's balance is prohibited, including: (maybe they was friends in our opponents)

Intentionally creating conditions for an enemy's victory, fixing fights with controlled results, deliberately losing any battle with the purpose of winning a Competition, and other forms of conspiracy."

Look the evolution of the score... it is not a player burn

they had launch lot of troups (without hero and shaman) against wall (LVL35 ennemies)

and the evolution of the influence of players (mad bunnies) (i take just exemple of one player... but all the team done the same thing)

You need also to look at the number of troups lost.

you really need to make the rules respected by the fraudsters ... we are a small kingdom and many players take a lot of their time and their money to develop their stronghold, and to win their kingdom... thank you.
