A week or so ago I started noticing some “sketchy” sites popping up on my TERRIBL Widget. When I checked them out I found no links to my site at all. After looking at my reports and log files and doing some experiments of my own, I figured out that most of these entries were coming from proxies, Perl scripts, and CURL calls and were completely bogus. So I started working on a way to automatically detect and block these and other invalid Referer’s from showing up on the sidebar widget. What I came up with was to do a callback to their site using the file_get_contents() function and scan their page for a link to the page in question. Then, only if the link was verified would the Referer be approved and added to the widget. After some testing on a few different sites using multiple methods for invoking these entries I felt satisfied that my new filtering technique was ready. So download this new version and let me know how it works for you!
This new feature introduced some new bugs too, so I have released version 126.96.36.199 to patch those bugs. I also added the ability to reset and recheck the link verification status right on the settings page.
