The reason of suspended accounts could be: No investment, only free play
This explanation fits to my case. I had my account suspended but didn't anything wrong but just took advantage of their free offer.
But I find it unfair because I also referred people who invested so they took some advantege from my membership.
Anyway I guess I already wasted too much of my time in this thread because is now so clear golden-cows is, at least, acting shady, not to say fraudly, towards investors.
