It was a long time ago I got banned. But I do think someone did log on my acc, Atleast I was logged in @ school. with a proxy from france so atleast there was a IP change. Second I have merged my currently active account with my banned account with my battlenet account. But as I said. I claimed to be hacked and even posted info of the Keylogger and everything. They did not beleive me and said "we will not look further into this bla bla".
