Please stop bumping older topics to the front merely to scroll the other posts down. It makes it very hard to keep track of what i've read and what i haven't. It's more annoying than the garbage posts are.
As more garbage posts appear you would have to keep bumping more and more to have your desired effect. The problem with this is that then old posts with no new information appear to be unread, and the rest of us must waste more time checking to see if there really is something new or not. In fact, we'll waste a lot more time doing that than we would simply by ignoring the garbage posts.
New genuine posts will appear on their own fast enough to take care of the problem. This is SONY's forum. Let them handle it.
