NeoGAF’s Twitter feed links to NeoGAF’s thread… which links to This (LOL WHAT!?) site. The gist is: If you want a free copy of Wipeout HD make an Austrian PSN account and you’ll get the code mailed to you (so you can’t use Spam.la for throw-away accounts)
Still, for a free $20 HARD AS HELL game you can’t go wrong putting a little effort into another account.
