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.
Sorry I wasn't clear. The deletion suggests that Clippy regrets the straight insults (though it could have been an administrator).
A permanent Clippy account provides no more cover than multiple accounts that are actually thrown away. In that situation, the comments would be there, voted down just the same. Banning or ostracizing Clippy doesn't do much about the individual comments. Clippy does represent an investment with reputation to lose - people didn't engage originally and two of Clippy's early comments were voted down that wouldn't be now.
The Open Thread posted at the beginning of the month has gotten really, really big, so I've gone ahead and made another one. Post your new discussions here!
This thread is for the discussion of Less Wrong topics that have not appeared in recent posts. If a discussion gets unwieldy, celebrate by turning it into a top-level post.
