I think with the naked short banned retail players have to satisfy their brokers that they've borrowed the shares. But hedge fund use no brokers and so no one to check them. They don't even need the proper broker license as I understand from researching how hedge funds work. This is why I am all in agreement with German officials in saying that hedge funds need to be regulated.
In the case of iSoft though there is one fund out of the UK that boasted how they've boosted their return by shorting iSoft. My guess is that AlphaTrader1 is somehow associated with it.
Whether there are other US funds or OZ funds doing the same I don't know.
