An email from Robert Schneider just confirmed that the post attributed to Jeff Mangum on the E6 Townhall is a fraud. In it he forwarded comments from Jeff, who wrote:

i am sorry to inform you that this is not my post. could you please inform the good people on the e6 list that this is not my writing?

Having fooled or confused Billboard, Pitchfork and myself, this might be one of the most successful message board hoaxes in recent memory. Sorry, folks.
