New Halfbakery Idea
The "Idiot" Button: Just like an ignore list, but more fun.
An addition to the Internet Bulletin Board button pantheon that would add a person to a new list - the "Idiot" list. Rather than ignoring someone, which removes their posts' text from your view (except when quoted, oddly), the Idiot list would simply put a slightly-large-font header at the top of their internet forum posts that says, "This poster is on your IDIOT list," thereby allowing you to read what they posted if you want, or ignore it if you want.
The IDIOT header would not be included in post-quotes (so people don't accidentally see who's idioted who).
Wait...idioted? Idiotted? Idiotized?
Nevermind.
When signing on to a bulletin board that supports the Idiot function, you could also choose to view all recent posts by those you deem idiots.
