Because it's hard to ignore someone who keeps muddying the waters of a discussion you're generally interested in. With online arguments you open a post from someone you're *not* ignoring and there's very often something in there from someone you are *trying* to ignore.
And people who muddy waters in the particular ways Dwayne is talking about revel in doing it for years and years.
