Looks like just about everyone's getting their bad self hacked these days. Since all the cool kids are clearly doing it, MTV has rushed to get itself hacked, doing so in such a hurry that it forgot about the very important step where you don't pretend like you've been hacked as a weird cry for attention. In fact, this move was decidedly risky, considering the Internet's typically low tolerance for bullshit. Also considering the fact that MTV's Twitter following doesn't seem to getthejoke. At all. (The fact that two of the three dumbest tweets I could find were posted by apparent Nicki Minaj acolytes is a complete, albeit utterly unsurprising coincidence.)
This type of marketing stunt might have been pulled off a little better if it hadn't been so suit-wearingly on the nose (wonder if any real hacker would gleefully mark each tweet with #MTVHack), and if MTV hadn't practically giggled through their hands while they told us IT WAS TOTALLY THEM THE WHOLE TIME LOL as soon as the stunt was over. Have a little faith in your audience, guys. Or don't, I guess.
Let's also not ignore the fact that Denny's showed up and totally owned the shit out of MTV's silly little campaign.
