You're being unneccessarily flippant and you're not even addressing the point. The point wasn't about short attacks, it was about "short ladder attacks". The person you're replying to is actually right, that explanation of a "short ladder attack" actually just generically describes short attacks and doesn't address the nonsense conspiracy of short ladders.

The short ladder attack actually is a stupid conspiracy. It's the idea that you can paint the tape by trading back and forth with a conspirator, but do it at a price that's lower than fair market value. This is impossible. If you try and buy at a price lower than fair market value you aren't going to be matched with your conspirator, you're going to get matched against the order book at the best possible price. So to ladder down you need to control the entire demand in the market. It's absurd.

Isn't that what they did with robinhood/others restrictions?
