I see that you can read my mind and my votes. Glad you have that ability

It's part of the Dark Arts package. I'll dryly observe that I knew you downvoted him - how do you think I knew that you downvoted him? It's not like downvotes come with names attached. Yes, I can "read your mind", which is to say, I read the -massive- amounts of connotation information associated with otherwise bland text.

Can you please provide evidence of what I am thinking and how I am voting?

You, uh, admitted to it? "I thought his comments were not worth attention"

Or who knows, maybe it was you. Hard to tell at this point. Not very familiar at all with these sorts of underhanded strategies and mind games and deliberate efforts to attack my reputation on Less Wrong, as you clearly describe here is your intention.

This paragraph feels passive-aggressive to me. If you think you got mass downvoted tell Nancy and she can ask Trike Apps for the perpetrator.

You realize that when you edit your comments, an asterisk shows up? Because I tire of your rather boring and predictable approach to Dark Arts, I'll go ahead and head this one off: I didn't downvote all of your previous posts and comments, I downvoted those here, in this post, where you were spamming. Additionally, a lazy look through your profile turns up several posts and comments which, quite definitively, were not downvoted. If your upvotes have taken a shock, it's because of your behavior, not a downvote bot.

http://lesswrong.com/lw/mvw/improving_the_effectiveness_of_effective_altruism/ for one example of a non-downvoted post from the first page of your posts. Given your rather blatant use of sockpuppets (or people from your organization told to upvote your posts/comments, which is the same thing as far as I'm concerned) for manipulating voting, the fact that it may get downvoted after I post this should not be taken as evidence by the audience of anything.

How do I know you're using sockpuppets or human analogues? Because your upvotes are consistent across a given timeframe without regard to comment quality. Which is also why you noticed the fact that some of your 4-upvote comments were downvoted, because you worked to get them to 4.

ETA: See the asterisk?

Also, any administrators are welcome to check my upvote/downvote history. If necessary I'll provide my password to an administrator to verify. (I'm not worried about being locked out of my account, because I can easily accumulate more upvotes, and anybody who dislikes me enough to want to do that probably wouldn't desire me to lose my heard-earned reputation for being an annoying blowhard.)

I did downvote some of them, but not, as a rule, those which engendered or contributed to the conversation.

And you apparently don't understand what I was "clearly" describing there, so allow me to be clear: I used an openly hostile attack because it meant the weight of evidence was on -your- side. All you had to do to have no damage to your reputation was to say nothing at all, and my tirade would have been taken as unfair and hostile. Instead, you doubled down on exactly the wrong behaviors.
