Or, may be somebody has already done - paykey.com site is no updates for long already, I have not.

Actually, the site has just had an update: they removed Senior Advisor David R Allen from the staff page.
This is the same guy whose primary role in Getgems was to manipulate investors into thinking that everything was going great with the company. And after the coin went bust, continued to spread misinformation for months to stop people from learning the truth.
David R Allen hadn't been seen in Getgems channels for several months... until a user today spotted him trolling under a different account.
He's allegedly now using the name/photo of the dog that can be seen in his personal youtube account.

These guys were crazy to try to scam 1.2m when their real ids are known. They are basically tainted forever. I hope some who got stung bad will never let it drop.
