Look to the lower left of the post, above the +Reply to Thread icon and you'll see a triangle icon with a ! in the middle of it.
Sorry if my paint skills aren't that great, but you can see the icon in the above picture. Just click that and give us a reason why you think the post is bad and we'll look into it.
