A broker tells a short seller that his client wants to sell. Then the shorter shorts the stock, then the broker arranges to sell his clients stock to that shorter. That shorter pockets $80,000 from all that dishonesty. Both only got a warning from ASIC.   Both those involved are well known in the industry.  Both parties received an enforceable undertaking in other words a slap on the wrist and no disincentive to stop doing it.

Warning****** reading the following report may produce some anger.
