Category LiveBookmarks Icon

CLB+ As many WordPress users now realize, there have been many fundamental changes in the new version of WordPress. The latest version of WordPress — 2.3 — features a considerably revamped database structure, including a complete reorganization and redistribution of the wp_categories table.

[ Image: Death-metal rocker drunk with power ]

Several days ago, I posted an article explaining how to hack your own WordPress nofollow blacklist. Immediately thereafter, I published an elaborate article focusing on automatic methods of nofollow blacklisting via WordPress plugins. 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

[ Image: Inverted Eye Detail ]

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 »

After our previous article, we all know how easy it is to kill the default nofollow attributes that WordPress automatically injects into all commentator, trackback, and pingback links. Indeed, our original one-minute upgrade delivers dofollow links across the board, effectively passing the love juice to every type of response. Fine for some, but some need more..

[ Image: Skeletor Blocks a Move ]

Figuratively speaking, hunting down and killing spammers, scrapers, and other online scum remains one of our favorite pursuits. Once we have determined that a particular IP address is worthy of banishment, we generally invoke the magical powers of htaccess to lock the gates. When htaccess is not available, we may summon the versatile functionality of PHP to get the job done. This method is straightforward. Simply edit, copy and paste the following code example into the top of any PHP […] Continue reading »
