Lol i got mine wiped by valve and then got the email that theyd awarded me the full set.
The irony was that far from being someone who had been innocently caught in the net, I had actually used the console commands to unlock ONLY the milestones thus leaving all my other achievements undone (so i could play with the weapons but still get the achievements properly). Apparently VALVe didnt look to closely at the logs they fiddled with
