In the last three weeks Blizzard was and he is one of the most hated and criticized game company.Yesterday I receive a message from one of my friend that plays Diablo three all time that he can roll back his auction.this is not all. You can rollback system date 2 days before and you can easy cancel your auction when you want.Now I will show you something that this company failed again and again.Read this and try it because is working.
So let.s say that we have two players.Amateur One put item on AH, Amateur Two buy that item, Amateur One just take money from the item, Amateur Two, go back with system clock before transaction. You get your money back and you can do this thing many times. I have news from people who made that like two billion of gold by this method in three or four hours. Good job blizzard you failed again and again.Some gamers are playing fair other are making money on your mistakes.Good job Blizzard.
