I really like the idea. I think if you provide some interesting statistics as example can make it viral. For example: how many spammy followers aplusk, techcrunch, mashable etc. have. How many of them are common to all etc., etc. This might get you a follow up article on techcrunch or the likes too. :)

Not to mention that having a birds-eye view of the spam situation will let him black list accounts, because a spammer is a spammer for the first user he follows as much as the next hundred.
