I don't mind bases that are nooby really, only when bad decons occur. However, I will often get in some helpful remarks to those builders.
When I do mind nooby builders, it's when I'm trying to build. Funny story (WARNING: MEAN STUFF AHEAD):
I was at Dretch*Tsunami, building away. About three others spawn as builders suddenly. After they start building horribly, I calmly tell them to not build, because I had it under control. Two of them listen. The other continues to build. I had used up a denybuild vote on a builder earlier. Now some other guy helps and tries. It fails. So, I tell the guy to stop building again. He doesn't listen. Then the others spawn as builders, AGAIN. I begin something that substitutes as "fun." I swap out my c-kit and start shotgunning anyone who spawns as builder and builds a dumb structure, in the face. Well after a while I had -8 or so, and a prettier base. The dude who kept up the noobishness the most was "WTF"ing at this point, and when he built another noob turret, I ran him through with a saw. He called a vote, and apparently that -9 didn't look so good.
Moral 1: Ask and ask and ask until they stop. (

Moral 2: Make sure that, when you're building at a totally public server, denybuild is a vote and you can vote multiple times.
