Beware of Crooked Steem Farmers

I noticed someone posting a rapid-fire succession of blog posts today and each one was quite long. I was impressed for a minute but that quickly turned to suspicion when I realized that I'd have to be Superman to type that fast, let alone think up the content and edit it. Curious, I dropped a paragraph from one of these posts into Google and sure enough, it pointed toanother person's post from another website. Only a few words had been altered in an insufficient attempt to throw people off the scent. I repeated the test with other posts from the user and found the same sort of results... I'm wondering if there's a way to identify and filter this sort of activity without us all having to manually check content like this? Probably not a huge priority but it's something to consider when looking to upgrade the platform.
