I had someone, I believe it was a mod, lazily flag a short, but valid answer of mine. If I recall correctly, I inquired (angrily) about the reason. Later I added some background to the answer to satisfy the complaint.
My comment is gone. Where is it. Who deleted it? Why was it deleted?
I have had this happen in the past on another answer, asked in chat and got no reply: https://chat.stackexchange.com/transcript/message/50844752#50844752
This gives me a very bad feeling of power abuse by moderators.
