Right. But we all do see them, so I guess you can skew the definition of “fake” and turn it into “real” bids and offers.

The study is incomplete because it doesn't show how much hft traders saves investors and retail traders by severely narrowing the spread between bid and ask.

Anecdotal but have you seen the recent spreads in volatile stocks? I followed the market in 2003-2005 when HFT was still a thing to ignore and I don't recall the spreads being different.
