Ok, (a) that is not what spoofing is (b) can you explain how a HFT possibly sees your order before it gets to the exchange? Do you think they are mind-readers?
You mean increasing iv when there is a lot of one/sided flow? I’m sure they do that (never worked on options MM myself so cannot be sure). As long as the info is ply incorporated *after* the orders are filled this is totally fine (both legally and morally).

Yeah. I mean I do not need a crystal ball here to tell you that the calls were being bought on Friday by retail, not by MMs.
