I have banned cd keys but is it possible to download something to play on Battle.net again.. and i dont mean open bnet.. I like ive heard shit about this d2 relived and other stuff.. i was wondering if it would work with banned keys since its not playin with the newest patch?

Once a keys banned its banned forever.

Yes, keys are banned forever but you can get a new one by looking at the official blizzard site

if you cd key banned 4 mh 1 time blizzard banned key for 6 monts ban another ban is 4 ever banned acc for using hacks nomather mh etc banned 4 evwe

How many times have you been banned? I don't think it is 6 months first offense, I thought it was 60 to 90 days, but give it a couple months before you try to log in again.
