There is something fundamentally wrong with allowing someone to a) sell shares they don't own (for future buy-back) so that they benefit from a decline in their value whilst b) at the same time giving them the tools (bot trading with non-commercial share parcels) to manipulate the share price downwards. It must be like printing money!
Try looking at the website 'www.asxinsights.com' for additional background, and make a point of signing the petition.
Then write a letter expressing your views and send it to :- a) the ASX (they will ignore it) b) ASIC (they have ignored all mine in the past; but they have a responsibility to maintain a fair market) c) as many senators and MPs as you can... especially the ministers.
After all; the ASX and ASIC are there to administer the rules (which arguably they fail at!) but the pollies are our representatives, and they collectively set the rules and have a responsibility to see that they are followed. Perhaps another Royal Commission !? ... A Royal Commission into the Share Trading and Brokering Industry.
