No it's not.... The game concept is in such way that you can't exploit anything if you have more than one account...
Let's see for example Imperia Online (the first IO's game) there if you have many accounts you can attack them with your main account and gain the resources for free (since you are not stupid enough to leave your armies slaughter each other...). Here there is an option by default with you can transfer gold and diamonds (credits) from one account to the other as long as are at the same realm.
Also you "must" create 3 accounts if you want to see what class fits you better.
And finally the game is based at Action Points, since one AP is given to you every one hour what is supposed to do when you run out of APs? forget the game for 5-6 hours? So it's better log in with your second account and continue playing until his APs run out too.
Honestly I can't think nothing more than guild leader elections which a multi-account player can exploit...
