The Team Fortress 2 Website has another scolding from the TF Announcer, who is dismayed to learn players are unlocking Team Fortress 2 achievements by cheating, forcing a few week-long suspensions:

This time it seems a number of you used an external application to unlock all of your achievements in order to get items unfairly. Coming as a surprise to no one with the ability to retain memories of the recent past, I have taken these items from the perpetrators for one week.

Can I trust that this episode has finally taught you a lesson? I should live so long. Having watched how the sorry lot of you comport yourselves on the battlefield and in the forums, I would consider it a small miracle to trust one of you enough to lick stamps without asphyxiating.
