I am the one responsible for the MediumIsTheMessage "sock puppet" account. I am sorry to see that people were offended or suspicious of it; I assure you my motives were decent and, though I did vote from the account 5 times (usually after having forgotten which account I was logged in with), it was never with an agenda, such as voting my own posts up (I never did that). I submitted a video because I thought I had to get off probation before I could post to sift talk. I was attempting to be as up-front as possible by giving disclaimers and explaining what I was doing. I really wasn't trying to trick anybody, so accusations of dishonesty really make me feel the depth of my failure. The ban was totally fair and I hold no grudge, but I am a bit embarrassed. I'm not much of a social scientist, I know, but hey, the first time you try to do something, you are pretty much guaranteed it'll blow.
