Yep, they are.
Here's how you access them:
1) Roll a character on a well populated server.
2) Create a guild.
3) Advertise your guild to get players interested in a pristine server.
4) Play the game with no heirlooms, don't use LFD and don't group with people who aren't in your guild.
Done, and done.
For those playing pristine servers, let me know how you get on.
