I have a site I kind of abandoned a little over a year ago, recently it popped up in a google search I did with the warning "this site may be compromised" So I logged into webmaster tools and there were no warnings... I thought that was odd. In going through webmaster tools I get to the keyword density report. The most common keywords are not anything remotely related to the site. Cialis, Viagra, etc are the most common keywords. But, I don't see them anywhere on the site. Not on posts, or pages, comments are facebook comments. The site has been compromised somehow would anyone care to share how they did it?
