Archiving an online source is easy, free, and prevents traffic and revenue on sites that are often less than desirable. Especially if you're posting the article to mock it, ARCHIVE it.

Additionally, this makes it impossible for the article to be stealth edited.
How to archive? Copy the URL and take it to the Wayback Machine or http://archive.is. The site will spit out a URL to the new archive, which you can spread without helping out the publisher.
