Can CRZ blocking get you banned?

[Ravenly]

Im sure Blizz are not particularly happy about people using peerblock and such. Anybody ever got banned for this?

You can do the same with windows firewall or a router firewall. Doubt it's bannable. It's not a "cheat" since you can do it without any 3rd party software or anything
It's basicly the same as if you would get banned for losing your connection :P
