I love Blizzard.
anyways after some research on the Original poster. turns out he was banned from retail for hacking and malicious conduct, ( he should learn to block his facebook page from strangers) later he found asylum on said private server where he was banned from hacking aswell.
I suspect that is unlikely.
seriously i watch blizzard (long time member starcraft) and they generally do not have issues with old patch private servers
The fact that such servers are not making much money off stealing Blizzard's intellectual property makes it a waste of resources to sue them.
That does not mean that Blizzard has no objection to people stealing their intellectual property.
heck you should read their post on EMULATION of their client and servers. very very loosely accepts old servers..
Anyone logging into a WOW account from a computer that has an emulated server on it will have their account instantly banned by Warden.
