If you’re following celebrities like Oprah , Michael Arrington , and Justin Timberlake you might find that folks are retweeting some odd stuff purportedly originally posted by the aforementioned celebrities. For example, I was watching Greg Grunberg AKA Matt Parkman from Heroes (and the co-founder of Yowza ) and noticed he was being re-tweeted with a vengeance. The tweet was simply ‘RT @greggrunberg guys watch”Transformers 2″ Movie Free online here [snip] Wal-Mart’ and it was sent out, in this case, by CarriCarrie012 . A few clicks

and we discover that young Carri is not “Goofy, intelligent, and determined!!!” as she claims in her bio but is actually a spambot. The bot essentially takes a celebrity’s @ name and pretends to Tweet that they are supporting the viewing of pirated versions of major motion pictures for free, something someone like Grunberg would never condone (although I wouldn’t put it past Oprah).

The rest is here:
No, Oprah Doesn’t Really Want You to Watch That Pirated Copy Of Harry Potter
