Yes, from personal experience, I can say that I have seen sources print things about me that were false and defamatory and upon my complaint, they merely removed it from the web rather than printing a retraction in the paper edition. In some cases, the false information remains on the web today (thankfully, obscurely) in archives of syndicators. I assume it will often remain in paid archives as well.
Funny how he's never asked me or any staff editors at Examiner.com to remove any of my content from the web. Probably because my content about him is all true
