WordPress Plugin Reveals a Black Hat's Network
A while back John Andrews wrote a post about trusting WordPress plugins and how that really isn't such a good idea. I agree with everything John wrote, but up until today I hadn't come across a plugin that actually did anything that "crossed the line".
The plugin that I've been digging into has code that randomly determines whether to inject a link into the outputted text. Not only is the insertion frequency dynamic, but so is the link that is injected. That is, the link is pulled from a website that when queried, spits out a different link. A nice automated link building tool, wouldn't you say?
After a few minutes of requesting links from this site, it became apparent to me that the black hat has just made it easy for me to identify 18 of his sites.
So what would you do with a list of domains all being supported by black hat link building techniques? Take the opportunity to learn a thing or two? Call Matt Cutts?
