Vampire War - iFree Studios (iPhone/Android)

Hey everyone, does anyone know any exploits/bugs for "Vampire War" made by iFree studios for mobile devices?
There are some "hackers" that are exploiting the game for sure and i want to know how so i can compete with them.
Its damn frustrating they always get rare items in no time, and have tons of silvers to spend.

Thanks,

Ciccions.
