I wasn't making an appeal to authority, I was noting that, like I said in my first sentence, Buzzfeed and Buzzfeed News aren't the same thing. I then go on to say, for whatever it's worth, at least one study in journalism considered Buzzfeed News to be quite good; I very clearly neither agreed nor disagreed with that decision. It should also be obvious to the reader that there aren't any studies in journalism on the accuracy of Buzzfeed listicles, which would relate back to my original point, that Buzzfeed is not Buzzfeed News, for what it's worth.
