Seriously, I've been hearing that comment ever since I started actively playing Blockland again (as I wasn't involved with the community before then, but my guess is that people were saying it then too.) If every time someone has brought this up, and many people agreed it was true, it was true, by now all builds would consist of 3 2by4s, and no posts in the forums would be legible enough to read. Sure, this is does happen, but it is not nearly as bad as everyone makes it out to be.
I think people need to think about the improvements in the game more often then they do. In the version I first played you'd pick up the bricks you wanted to use from a small pile, and have to build on the baseplates that are a part of the map, now we have wrench events and physics, something that wouldn't have been dreamt of by the builders who got mad while some random person came into the server and destroyed their several hour's work with a hammer and couldn't do much to stop them.
