Stop WordPress from Leaking PageRank to Admin Pages

During the most recent Perishable Press redesign, I noticed that several of my WordPress admin pages had been assigned significant levels of PageRank. Not good.

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 »

[ Image: Skeletor Blocks a Move ]

Figuratively speaking, hunting down and killing spammers, scrapers, and other online scum remains one of our favorite pursuits.

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 »

Take Good Care of the Puppy

Of all the bizarre, nonsensical, and pointless spam we have received so far this year, this one takes the cake. It was delivered to our designated spam account earlier this month as a plain-text email, which opens with an explanation. Apparently, “Bob Diamond” is “an Hiring Manager” looking to advertise a couple of important items. The first ad seems remotely realistic, but the second ad.. it’s like, “teddy bear features” out of nowhere — you can’t be serious. Continue reading »

Invite Only: Traffic Control via Whitelist

Web developers trying to control comment-spam, bandwidth-theft, and content-scraping must choose between two fundamentally different approaches: selectively deny target offenders (the “blacklist” method) or selectively allow desirable agents (the “opt-in”, or “whitelist” method). Currently popular according to various online forums and discussion boards is the blacklist method. The blacklist method requires the webmaster to create and maintain a working list of undesirable agents, usually blocking their access via htaccess or php. The downside of blacklisting is that it requires considerable […] Continue reading »

Industrial-Strength Spamless Email Links

Add RSS Feed Link Icons to WordPress Category Listings

Category Links via wp_list_categories()

This brief tutorial explains two methods for adding RSS feed link icons to category listings. Let’s say that you have a list of category links, where each link targets a specific category view.

So, rather than cluttering up your page with two sets of category links — one for category views and another for category feeds […] Continue reading »

Extreme Makeover for Gravatars in WordPress
