O.K. This is a really old subject, but doesn't seem to have been mentioned in a while, so assuming most are not having the problem now or not complaining about it here anymore.

Never happened to the clan before, and mostly they have been fairly reasonable opponents , but the next opponent is way out of our league.

We don't win that often,but we did win the last  one, but we are very much less than a billion, and the next opposition is 152 billion. 

How can a clan of nearly 153 billion be in the League of Rookies?

Additional information.

I would suggest that this clan consists of 1 person opperating many other accounts and using some scheme to gain an advantage.

Especially given additional information , which suggests its more than  just circumstantial evidence.
