Just recently, a user asked a question that I ventured to answer. I spent a bit of time cobbling together the logic and posted what I thought was a correct answer.
Today, I think I'm having deja vu as I see the same question as last night. I search for my answer and it is nowhere to be found. I conclude that the OP deleted their question with my zero vote answer and asked again as pandas: expanding mean based on conditions & excluding current row.
My question to the community is, Is this acceptable behavior?
I understand that my answer may not have answered the question. But wouldn't it have been better to ask a follow-up question?
Either, OP is acting appropriately and I need to get over it (which I will). Or, they aren't. If they aren't, what should I do? Anything? Should I ignore it? Or should I try to politely educate them on etiquette?
