Like, I'm not trying to avoid the knowledge that I often make contributions to LessWrong that aren't well-received. It happens, more for me than for others. I was just pointing out that I've also noticed strict karmassassination sometimes, not necessarily often in my 2190 most recent comments. It's just a thing to take into account. The karmassassination I have experience with is often not of the sort that you describe. But I'm perfectly willing to accept such explanations sometimes, and I've already noticed that they explain a few big chunks lost a few months back.
