if it was banned or not without installing?
Is there a way?

Im going through like 20 keys and most of them are banned and its annoying reinstalling with all these keys haha.

Try register them on blizz.net/store,
but if u are findiing them on google , no luck bro.
most of them arent registable on b.net

eh to mcuh registering because i would need multiple names on blizz
Im not googling them I actually own them from over the years and old friends that quit .

thanks though

Only can register 1per account ( 1 sets )

GL bro
