The entire DiRT3 key collection from an AMD offer, approximately three million keys, has been leaked to the public. The keys are for Steam only, yes, the keys are valid but we are waiting on what Valve or Steam will do, blacklist the keys; VOID them or, nothing at all. A post on the Steam Community forums lead to the discovery:
“unfortunately, complete AMD promotion key list leaked to internet (around 3 millions DIRT 3 keys) I assume that proper course action will be simply blacklist every key and remove them silently from accounts then tell users to re-register new ones or … do nothing, In short never put .sql database with game keys on webserver where simple missing .htaccess can leak it”
The keys are only good while they last on a first-come, first-served basis.
