I'm not sure that what Gleb wrote is a good example of tell culture. However, karma anomalies (especially negative karma anomalies) is one of the things I need to hear about. I don't as yet have a strong opinion about whether they should be mentioned publicly or messaged to me, though I'll note that I'm more likely to see personal messages.

In general, I've come to believe that if your mind goes to a single negative motivation for an action you don't like, you're probably at least missing some nuance, may just plain be wrong about the motivation, and could be doing some inappropriate obsessing.

To be clear: If you do anything other than the simple task of being open about your activities (by making a list) right here and now you would be betraying your interests by demonstrating that you are not being open about your actions.

I am comprehensively squicked by this, though not at the potential ban level. I'm not sure whether you've made an inappropriate demand for rigor, but it does seem like an invented and intrusive standard. You are not in charge of Gleb and you are not in charge of Tell culture.
