Screams of the Past is one such guild. Check out what Zwinkz had to say about their efforts:
We're the only classic guild that has remained 'pure' when it comes to raiding. Meaning anything that was introduced after Classic is not allowed when it comes to raiding that includes Glyphs, WotlK enchants, and gems. We're still bringing a great roster clearing all classic content available today including AQ40, 2 BWL Raids, 2 MC Raids a week, as well as AQ10. I feel we are the players that stand for a true classic guild.
While vanilla raiding may not be your thing, you certainly have to respect their dedication to the playstyle.
