Never ever, in the history of Internet videos, has a user-generated video hosting site been avoided by those who wanted to share their triple X rated clips with the world. The rules are already classic and have been around ever since man climbed down from trees and discovered the power of marketing: the first to come is the first to be served. Abiding by them, the latest video site to surface is the latest one to have been 'given' the not safe for work (NSFW in short) clips. Drumrolls, please it's Yahoo! Videos to have the dubious honor!
The filter problems that YouTube experienced when it first opened its doors - its servers, actually - have come back to bite Yahoo! in the rear, just because it is young and inexperienced. Two clips are now hosted on the Sunnyvale based company's video sharing service, and have received all the attention: one is of Jenna Jameson, a woman, a star that needs no further introduction, and the second is equally provocative and enticing, but the protagonists are not as well known.
The clips seem to have been around for quite a while, judging by their number of views (above 6,000 as I write this), and are viewable by accessing the "Health and Beauty" tab in the Category view of the video sharing site. The screenshot shows that they're not difficult to get to, kudos to them for making top page. Others can be found via the related videos section, but I decided to single out just the two based on the above argument.
As one user commented on Valleywag, there's a new XXX video site to browse when at work, and it's got the Yahoo! logo up and visible, so there's a perfectly good excuse for those caught watching. Just hit the button and scroll up to where the Y! is placed and there's no need to worry.
