I cannot provide links, unfortunately, no, because most of it happened in background threads, although MugaSofer's comment can be taken as confirmation that this was, in fact, being talked about. This was a... semi-popular topic on how Less Wrong could be improved around that time, when I happened to be unusually active, although I left in disgust right before Eugine's ban, IIRC, over the fact that my most upvoted comments were what I considered basic-level social sanity, and the stuff I wrote that I expected to be taken seriously tended to get downvoted (later I realized that Less Wrong is just incredibly socially inept, but relatively skilled in the areas I expected to be taken seriously, so comparative advantage went overwhelmingly in favor of my social skills, which happened to be considerably better than I had thought at the time). Eugine didn't invent the idea of mass-downvoting, he merely implemented what was being discussed.
