@matigo yeah I don't know what that means or why it happened. Either a fluke, or part of the attack I faced on my blog last year or so. The hacker was able to modify MySQL files to add random URLs to my posts, in a very native manner, making it VERY difficult for me to detect them. I'm still cleaning up that mess today. I think 'compilations' happened either when I moved from wp.com to .org a LONG time ago, or some back backup, or was part of this hack.
