Over 150 of the Worst Spammers, Scrapers and Crackers from 2007

Over the course of each year, I blacklist a considerable number of individual IP addresses. Every day, Perishable Press is hit with countless numbers of spammers, scrapers, crackers and all sorts of other hapless turds. Weekly examinations of my site’s error logs enable me to filter through the chaff and cherry-pick only the most heinous, nefarious attackers for blacklisting. Minor offenses are generally dismissed, but the evil bastards that insist on wasting resources running redundant automated scripts are immediately investigated […] Continue reading »

[ Image: anonymous junkie shooting up heroin ]

If you are using Feedburner to deliver your feeds, chances are high that most — if not all — of your loyal readers have subscribed to the Feedburner-specific version of your feed’s URL. This is not a good idea for a couple of important reasons: Complete content-delivery failure if/when Feedburner goes down Cohesive branding strategy impossible because visitors see Feedburner’s name in feed URL instead of your own At this point, millions of feed subscribers have Feedburner-branded feed URLs listed […] Continue reading »

Important Note for Your Custom Error Pages

Just a note to web designers and code-savvy bloggers: make sure your custom error pages are big enough for the ever-amazing <cough> Internet Explorer browser. If your custom error pages are too small, IE will take the liberty of serving its own proprietary web page, replete with corporate linkage and poor grammar. How big, baby? Well, that’s a good question. In order for users of Internet Explorer to enjoy your carefully crafted custom error pages, they need to exceed 512 […] Continue reading »

Are Adblock-Plus Visitors Seeing Your Content?

[ Screenshot: Adblock Plus Ruleset Filter Option Panel ]

As Firefox continues to grow in popularity, it is inevitable that more and more users will install plugins such as Adblock and Adblock Plus. As we know, such extensions work by filtering site contents through a list of predefined wildcard directives and other rules. Users may also customize the block-list by right-clicking on unwanted images or even subscribing to an automated filterset updater. Apparently, a significant number of Firefox users employ these extensions to help control the relentless flood of […] Continue reading »

Yahoo! Slurp in My Blackhole (Yet Again)

Yup, ‘ol Slurp is at it again, flagrantly disobeying specific robots.txt rules forbidding access to my bad-bot trap, lovingly dubbed the “blackhole.” As many readers know, this is not the first time Yahoo has been caught behaving badly. This time, Yahoo was caught trespassing five different times via three different IPs over the course of four different days. Here is the data recorded in my site’s blackhole log (I know, that sounds terrible): Continue reading »

Yahoo! in my Blackhole

Okay, I realize that the title sounds a bit odd, but nowhere near as odd as my recent discovery of Slurp ignoring explicit robots.txt rules and digging around in my highly specialized bot trap, which I have lovingly dubbed “the blackhole”. What is up with that, Yahoo!? — does your Slurp spider obey robots.txt directives or not? I have never seen Google crawling around that side of town, neither has MSN nor even Ask ventured into the forbidden realms. Has […] Continue reading »

How to Verify the Four Major Search Engines

Keeping track of your access and error logs is a critical component of any serious security strategy. Many times, you will see a recorded entry that looks legitimate, such that it may easily be dismissed as genuine Google fare, only to discover upon closer investigation a fraudulent agent. There are many such cloaked or disguised agents crawling around these days, mimicking various search engines to hide beneath the radar. So it’s always a good idea to implement a procedure for […] Continue reading »

Suspicious Behavior from Yahoo! Slurp Crawler

[ Image: Black and white illustration of the upper half of a man's suspicious, paranoid face ]

Most of the time, when I catch scumbags attempting to spam, scrape, leech, or otherwise hack my site, I stitch up a new voodoo doll and let the cursing begin. No, seriously, I just blacklist the idiots. I don’t need their traffic, and so I don’t even blink while slamming the doors in their faces. Of course, this policy presents a bit of a dilemma when the culprit is one of the four major search engines. Slamming the door on […] Continue reading »

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.
