In this article, I expand on the original blacklist hack by incorporating functional differentiation between commentator links, trackbacks, and pingbacks. If anything, think of this as an exercise in hacking WordPress, rewarding in and of itself, if not otherwise entirely impractical. Of course, whenever possible, you should […] Continue reading »

Hacking WordPress: Dofollow Whitelist for Commentator Links

Before repenting of my filthy “nofollow” addiction, I experimented briefly with a “dofollow whitelist” for commentator URL links. The idea behind the whitelist is to reward frequent commentators, feed subscribers, site patrons, and other guests by selectively removing the automatically generated nofollow attributes from their associated comment-author links. For nofollow enthusiasts, a dofollow whitelist is a great way to show appreciation for people who support your blogging efforts. Now, before we go hacking away at WordPress, keep in mind that […] Continue reading »

WordPress Plugins Featuring Nofollow Blacklist Functionality

Here are a few priceless examples of actual spam (i.e., linked) comments left here at Perishable Press (links removed for […] Continue reading »

Another Mystery Solved..

Recently, after researching comment links for an upcoming article, I realized that my default <input /> values were being submitted as the URL for all comments left without associated website information. During the most recent site redesign, I made the mistake of doing this in comments.php: … <input class="input" name="url" id="url" value="[website]" onfocus="this.select();" type="text" tabindex="3" size="44" maxlength="133" alt="website" /> … Notice the value="[website]" attribute? It seemed like a good idea at the time — I even threw in a nice […] Continue reading »
