Op, maybe you can try to report some of his posts and see what moderators will do about it, otherwise ignore the user.
I've reported 2 of his topics yesterday. One is good (removed), one is unhandled (may or may not get removed, probably not).
Since I've only started reporting him, it's not that bad. However, the more reporting those mindless posts, the more chances to get removed. Maybe someday he starts writing something thoughtful.
What you should do is put him on ignore ASAP and don't even peek at what he writes anymore, because you'll just get frustrated. Believe me, it'll save you mental stress that you don't need.
While ignore worked for me very good, I think that reporting at least the worse ones can be a good course of action too (now it's unignored).
However, I agree: if it becomes too frustrating, then the solution is ignore.
