Standard reply: First, the practice experience from wow-power-lvl.com and the feedback information from above 100000 customers proved that: 95% of banned account owner can ask it back from blizzard

The method is :no matter blizzard banned it by what reason you may request the blizzard to provide

the reason and the evidence for banning, the blizzard couldn’t put out the evidence . In fact the blizzard decided to ban the account only by that company’s suspicion . it is irresponsible and doesn’t have reason.

Usually under the intense request of customer above three times .they will compromise to give the account back to the customer.
