Ao3 writers can be such snowflakes. A year or so ago I made a lengthy comment on a fic I liked, pointing out some glaring and basic flaws in MC's strategy and suggesting corrections and alternatives (of the grammatical and strategic variety). My comment disappeared, which made me think that perhaps I accidentally deleted my comment, or that I had not posted it at all.
So I typed out everything, again.
