It's hard to imagine a more wasteful form of spam. Gratuitous video! This evil goes to 11. It's like the bandwidth-thief version of billboard trucks.
I hesitate to link to a spam page, but check this shit out! Apparently the spammers are now taking the title of one (real) Youtube post, the description of another, and the video from a third -- then pre-pending some textual spam bullshit to the front of the video itself and re-uploading it. (And I'm seeing lots of these because they keep mentioning DNA Lounge.)
