Personally, I am pretty certain that is gender issues that cause my karma stalking. It's the only topic I write on that gets any significant number of downvotes. Also, due to timing, my best guess (though I'm not highly confident) is that the triggering event was my post in the mistakes thread admitting to staying married longer than I should have due to not being confident in my independence. I knew when writing it that some of the MRA assholes on here would take offense at it. Also, whoever is doing it has pretty effectively made me unlikely to post a lot on here. (I still occassionally browse, and obviously I'm writing this, so it's not like I've completely quit or anything.) It's annoying to deal with (and saying "you should just stop caring" is about as effective of advice as telling people to "be more confident"). Considering that half my facebook feed is rationalist/LWers anyways, it's higher reward to just post my thoughts there and not have to deal with the LW baggage, but still get the interesting conversation with the people I want to talk with anyways. Just figured I should say something because if evaporative cooling is happening in general (and it isn't just me), it could be hidden because the people who leave aren't saying anything. (ETA: I actually have not lost a LOT of karma from this, so it's not the amount/number. It's just the fact that it's consistent, and it's everything I post)

You can count me as another member who has both been block downvoted, and suspects Eugine Nier as the most likely candidate based on my patterns of downvotes received when I participate in conversations or debates with him.
