I saw this on NeoGAF and what the hell, it can't hurt right?

Take a look at the OP and let Sony know what you think. The following is from GAF.

My biggest piece of advice is be respectful. They aren't likely to finish a tweet in all caps threatening them. 

Shuhei Yoshida (president of worldwide studios) @yosp (easily the highest level person on twitter and quite accessible)

John Koller (head of hardware marketing) @jpkoller (dude has like 150 followers - heh)

Guy Longworth (senior vice president PlayStation Brand Marketing) @luckylongworth

Scott Rohde (PlayStation Software Product Development Head for Sony Worldwide Studios America) @rohdescott"

#PS4NoDRM #PS4USEDGAMES  are the hashtags being used.
