Blog Spammers Using URL Encoding

I was getting hit by comment spammers in the last week who were using URL-encoding of their addresses to get around the comment blacklisting filter I use. By replacing regular characters with the multi-character encoded representation of those characters within the URL the spammers were able to post comment spam …

Blosxom - Default Flavour Plugin - Fixes Unknown Flavour Error

I previously blogged a solution for the Unknown Flavour error that involved modifying the blosxom.cgi script itself. I recently found my modification caused requests for the RSS 0.91 feed and atom feeds to return the default flavour instead of the desired feed. I suspect any plugin using a …

Blosxom - Hit Counter and Favorites Plugins

I added a Favorites page to the side menu of my AgilityNerd site. Since then I've been updating it manually about once a month based on the AWStats reports from my web hosting provider (HostMagix). This task is unnecessarily complicated because AWStats keeps page counts independently for each URL, which …

Blosxom Plugins: lastcommented and lastread

In preparation for an overhaul of my website I wrote two new Blosxom plugins. The lastread plugin allows me to create a list of links to the last n articles that were viewed by readers. The lastcommented plugin allows me to create a list of links to the last n …

Blosxom - Removing the Unknown Flavour Error

After my recent Referer Spam attacks I've been checking my logs and AWStats reports daily. I noticed that occasionally I'd get people requesting pages with incorrect suffixes. i.e. foo.ht or bar.|id| (some of these are probably spammers too). A "feature" of Blosxom is that it will still …

Comment Spam and wbcaptcha Plugin Enhancements

I have been fighting automated comment spam robots (see also refererblock update, and hit counter changes) with my modified writeback plugin that uses a blacklist of spam words and URLs. However, I'm getting tired of updating the blacklist and removing spam comments that get through the filter. So I decided …

Directing Search Engines to Blosxom Content Pages

I've noticed that folks who come to my site by querying through a search engine often end up on my main page and the article they are searching for has already rolled off the front page. This is because the search engine robots tend to choose the index pages as …

Image Theft Ranting And Blocking

I was really disappointed yesterday when I checked my blog's statistics and found that someone from a Hungarian Agility discussion board had directly linked course images from my website. Direct linking of an image is placing the URL of the image directly in a webpage hosted on another server. Each …

Modifications to Blosxom entriescache PluginHandles Articles With Future meta-creation_date

Fletcher Penney created the original entriescache Blosxom plugin. It is designed to cache all the articles and their creation dates in a Blosxom blog to avoid the overhead of scanning the file system for new/modified files. He merged the meta plugin functionality into the plugin to allow authors to …

Refererblock Version 0.2

I came up with two improvements to the first release of my refererblock plugin:

  • If the referer string matches the site's URL it passed immediately and isn't checked against the blacklist.
  • The blacklist.txt file was being read even if the referer string was empty. Now it is only read …
