It was not much of a punishment. He was simply not invited to the ceremony. If he had been disqualified, now that would've been an appropriate punishment. An even better one would've been disualifying the whole movie, as the campaign went into effect and influenced people's decisions.

The Oscars have went the opposite route of the Grammys: they award small indie movies that no one watches, that are pretentious, and seem important because they're about major "issues" even though they can be of poor quality (Crash, The Reader), while ignoring mainstream movies, even if those movies are very good (Star Wars, E.T., Avatar etc.). At least the Grammys are less predictable though. My fav awards show last Year in terms of winners was the Emmys, Mad Men and Modern Family FTW!). The Grammys had OK winners (though I hate Taylor Swift), and the Oscars were simply terrible and predictable. I wasn't impressed with The Hurt Locker, and found it to be the standard war movie that wins a Best Picture Oscar (not to mention that I was simply disgusted by the fact that they nominated it for it's non existent score, and gave it the sound Oscars over Avatar, and the screenplay Oscar for it's terrible terrible screenplay, instead of Inglorious Basterds ).
