We actually had a "Dumb" topic icon during the first iteration of the phpBB forums, but Black Squirrel removed it after The Split (probably because he didn't want to encourage people to make "dumb" posts):
Feel free to make more topic icons, but I can't guarantee that we'll add them, since we already have a lot of topic icons, and people don't use them much. In the long run, we'd be more likely to replace the topic icons with a newer system - such as a post tagging system, especially if it helps SEO.
