Lunamine was not paying "non variable" amounts. The increments timings and amounts were consistent with blocks being found with some variance.
You speak as though you were with them from the very start of their operation which wasn't all that long now was it !?!
But if you have payouts to back up your statement then I'll bow to your greater exposure to Lunamine's system !
Like everyone here, I'm sure we'd all love to hear from him/her/them, however, the longer the silence the less likely of it being anything other than a Crime eh ?
