Just some PPC ad company, a lot like AdBrite. www.adengage.com - they're okay, but it was supposed to be an insult to YPN. On a sidenote, my Yahoo ads aren't showing all of a sudden. ANyone else getting the same thing? edit: nevermind, theyre back. probably an evil conspiracy.
Is there a place where it lists the correction amounts, or are your stats just updated? I haven't noticed anything change.
