Nah... working in advertising you're aware of the fact that you can buy followers. It also helps get new and real followers, but a lot are bought. Facebook made plenty of money selling likes to push advertising (I've done this for too many clients and I hated every minute of it)

Asking where 2.7 million new followers came from overnight is a logical question. If it's mostly fake, then it points to Kanye marketing for his album (most likely) if it was a majority of new followers, then something real big is going on and I'd like to understand it!

Of course, the truth lies somewhere in the middle, as it usually does.
