(Yet) Another new spam attack

In the wiki, someone posted on the main page a seemingly-invisible attack on PageRank. Fortunately, I can easily check the wiki's diff for a particular change, and catch this crap early on. </p> <p> Some chump went into the main page, and added a div that's 1px tall, contained with a large group of links for yet another drug. Looking at the page, you don't see anything. However, when Google indexes the page, it'd catch a whole lot of links to these sites. </p> <p> Very clever. Thanks for pooping on the Internet, and adding yet another todo item to my already-crowded list. Jerks. </p>
