Are you an idiot? You can't call a system a scam based on a single month.

I've been trading Z12 for a bit over a year now and I'm sitting at 50% profit: http://www.myfxbook.com/members/bobobo1618/mt4-985808/2833415

It would have been higher if I'd monitored the server controlling it better.

I also have an older account that was profitable: http://www.myfxbook.com/members/bobobo1618/z12-ea/1684780/HEpTBW544fYpy2oZZzoe
