G2A is still determined to show that it can do right by developers worried about shady game key sellers. The online marketplace has introduced a new verification process that should make it harder to commit fraud. New sellers will have to provide a legitimate phone number and social networking account to get their foot in the door. Also, they'll be limited to selling 10 products before they have to deliver more proof. This is just the start, G2A adds, as "further measures" are planned that will check addresses, credit cards and PayPal accounts.
