Those are spam-bots. They've got some kind of script that scrapes a sentence or two off someone else's post, then uses that to put up a post that appears legit so as to fool you into not reporting it as spam. Sometimes I think they even have spam farms full of real people who do it. If you click the reply with quote, you'll see the links exposed where those red x's are and see that it's spam. They're just trying to spam the world with links so as to increase their rankings in search engines. I click the death triangle on them and sometimes the moderators will remove them, sometimes not. They need more moderators around here.
