Question about Lurker guilds and servers

[VoiceMan]

I'm interested in playing WoW again, but I'd like to play Alliance on a PvP server. Is there a big Lurker presence in any such server?

What's the biggest Lurker presence on any type of server? PvP or PvE, Horde or Alliance?

Also, what are the requirements for joining a Lurker guild? I think I can pass a urine test.

I'll let the Alliance players respond in more detail, but to my knowledge there's not a big Lurker presence on a PvP server. I believe Stormrage still has the biggest Alliance side guild of Lurkers, and it's a "Normal" server.
