I too would encourage anyone who participated in this GB to add a negative trust so others don't suffer the same fate.
Ragin is either a scammer or has a mental disorder combined with incompetence/laziness, in this instance the GB participants were extremely lucky. If Yifu didn't screw up chip orders and offer refunds, they would likely have
NOTHING. No (worthless) chips, no boards, etc. His stories were fake (ask him to produce an obit)... you can't very well speak ill of someone who has lost a family member or ask them to "prove it" and he has an extensive track record (check hard forums) of "issues."
I would encourage anyone who participated in this GB to add a negative trust so others aren't duped.
