Corruption is a synomyn for Stock Market. Naked shorting is a known allowed process where shorts can be borrowed that are not available for borrowing, and they don't show up in the % Short Interest. Short interest on AMC has been displayed at 20% when the estimates that included naked shorted was estimated at over 100%, that was the reason for predicting MOASS, Mother of All Short Squeezes.
Cytodyn has been a target for shorting, and is broadcasted by famous Short trainer Tim Sykes, as maybe their biggest success. See Twists on youtube. Tim Grittani (spelling?) claims he made over $220,000 on that short of CYDY in June when we went from 9.87 to 3.45 or something in 8 minutes.
