As it stands in the OFFICIAL CLASSIC TERMS OF SERVICE from 2012, communicating with the opposing faction is explicitly against the terms of service and is a bannable offense:
That EULA isn’t valid. The one you clicked through when you installed the game is the one that applies. AFAIK there is no Classic-specific EULA so the retail version is the operative one.
You can find the current EULA on Blizzard’s web page. I searched through it quickly but couldn’t find anything related to cross-faction communication.
These guilds are not only going against the ToS with the collusion between them, but i have actively seen a HUGE chunk of their members Auto Macro afking Qia in Winterspring, instantly buying her plans the second they come up with no human interraction in the slightest, they’ll sit there for 8+ hours not moving, not responding, even getting killed, they’ll just stay there dead. Blizzard please do something about this, as they are ruining the game for everyone.
Sure, what are you going to do about it? Hide behind blizzard? You’re going to have to see the entire server banned lol. Little carebear wants to solo in peace. Not going to happen.
Yea I remember a long time ago ppl were getting in trouble banned for doing some thing cross faction with pvp. I wish I could remember like during BC like arenas or BGs.
