there is no such things as stop loss hunting, if it existed it would create the worlds biggest arbitrage opportunity.
Think about it, you have the real market on one screen, the CFD on the other, the real market stays put whilst the CFD goes up/down to hit your stop loss. Any decent trader would simply fade the CFD move knowing it was a fake creating a risk free trade. The kind of traders doing this would also be using a lot larger volume than the $1 a pip that most of there other customers. So in 'stop hunting' they would actually be increasing their risk.
