DISQUS

Andy Beard Tom I would say defending against that kind of plagiarism is more a Copyscape function with their sentry service, but that becomes quite expensive.

The best way to deal with people using your content isn't to fight it, but take advantage of it by including lots of deep links in your content, and be careful to block any trackbacks from the scrapers.

In my experience most of the scrapers actually send trackbacks hoping to get links, and a good number actually give real links, and although they are low quality links, it is still useful.
