Considering how worthless the rating system is, and how people have already been discussing ways to change it, I don't think this is a problem.
One person ranking everyone with ones is not going to ruin all of the people who listen to the files who will rate it higher than that.
On the other hand, I've found myself recently filtering out files by Haxsaw when I'm trying to find new files. This is like what happened with Stephen King, it's difficult to find any files not by Haxsaw on the new page and it makes me overlook anything he posts regardless of whether or not I would have normally found interest in it. Maybe he needs to do what Stephen King did and start pretending to be somebody else for some his other files? I wouldn't be surprised if someone rated everything he posted with a one just out of spite for this.
