I found that the part about Romney, which I do not know about and do not necessarily want to know about, gave me the feeling that the article was written with a political agenda. Then much of my interest vanished.

He says in the article that there's no authentication for buying followers and mentions the possibility of Mitt Romney's new "followers" being paid for by his opponents.

This has actually potential. Faking the opponent's social media followers/likes and "informing" the media about it could become a new tool in the dirty campaigning tactics arsenal

I thought it was interesting ... if there was any arena where social media is ripe for abuse it is the political one. The graph definitely makes things look suspect.

Of course, that doesn't mean the Romney campaign is behind it -- they could be, or it could be some fervent supporters, or, as the article points out, even his opponents designed to make him look bad.
