hmm.. without Blizzard there is nothing for me to play on my PC, so, no, I won't be boycotting Blizzard, even if they banned my years old D2 account I haven't used for uhmm.. years
and I'd be even happy if they banned my WC3 account, for I'm a bit too addicted to DOTA...
edit: *sigh* sadly I haven't been banned from WC3..
