Perhaps these are the 10am-4pm posters?

Consider the risks faced by retail traders shorting LYC by using a margin loan when the company's survival is at risk...

If the Stock goes into a trading halt it would become impossible for a short position to be closed! (shares have to be bought to close a short position since the previously borrowed shares have earlier been sold)

If a short term margin loan was also involved in the Short position this one failure could send the retail trader bankrupt when the margin loan was inevitably called in by the lender! With the traders position funds frozen new cash would have to be found to meet the margin call! The very fact that the money was borrowed in the first place probably means that the trader does not have it readily at hand. It may even be impossible to meet by quickly selling everything they have in the market so they become insolvent.

There would be no way out for the retail trader except new cash and the margin lender would not care if the retail trader went broke! It happens all the time! Small wonder that short positions are winding back IMO ...
