Are the kind of posts that flatearther43.2 is making in CN (ones with gigantic images and huge amounts of line breaks, both of which essentially render the thread unreadable) considered to be against the rules and/or otherwise prohibited? If so, then he should be getting warned or banned for it like with any other offense, instead of his posts simply being edited and nothing else. He's not going to stop if there aren't any consequences for his actions. Also, we might want to make it more clear that what he's doing is against the rules, because right now it seems like only junker is editing those posts.
For what it's worth, I'm entirely in favor of prohibiting such crash-your-browser posts. They're far too disruptive, even for CN.
