Trolls seek to engage; I consider that when deliberate dickery is accompanied by other trolling, it's just another attempt to troll.The dickish comments weren't deleted when I made the post. As for "cover", I guess I wasn't explicit enough, but the phrase "throw-away account" is the key to understanding what I meant. I strongly suspect that the "Clippy" account is a sock puppet run by another (unknown to me) regular commenter, who avoid downvotes while indulging in dickery.
