I would give him a week ban, he's been spamming for the past few days INTENTIONALLY which I think is a good reason for a week ban, or even longer. This also isn't his first streak of spam posts, he did the same thing awhile back. It's irritating seeing a bunch of IM posts on here because he wants to spam his way to the top.
