Visitors to Stage6's main page were redirected to multiple "shock" sites, like the famous goatse and 2girls1cup.
A pop up was added stating that the site had been hacked by Ebaumsworld. It's unknown if they had any involvement with the hacking.
Several threads on Ebaumsworld and various forums have been deleted regarding the attack. Posts like "Why did you do this?", "What did they do to you?", but also threads with verbal insults against the site.
This incident lasted about two and a half hours before a site maintenance notice was put up by the Stage6 admin team.
The main site of Stage6 was replaced with a message stating "We're unable to service your request.".
UPDATE: Stage6 is back up! If you haven't tried this site before go check out the top rated videos >> Here Youtube.

Wikipedia reports that "A partial list of email addresses and passwords for several thousand Stage6 users was released by hackers shortly after the attack began, in the form of a plain text file posted to 4chan's random board. The file has since been removed from the site."
Users that had registered a new account at Stage 6 between December 11th, 2007 and February 9th, 2008 were mainly those who were affected. There is talk, however, that the hacker(s) may have had access to the entire Stage6 user database.
Like Youtube & other video services, users are able to upload videos and share them with others.
Stage6 is known for users uploading full copies of movies that are still in theaters, many in HD quality. They do comply with all take down requests when copyright infringement is in question.
Many users utilize temporary e-mails to create multiple accounts to stay in ahead of bannings.
