As much as it seems likely that game-key selling sites like G2A have benefited enormously from stolen cards being used to buy and sell games on its marketplace, it's not a practice that can hope to continue if these sites want to remain operational.
With that in mind, G2A has now implemented a new system of verifying key-sellers before they can go ahead and transact with the site's many members. Now, before you can sell on the site, you need to provide your social networking information, a contact phone number and several forms of identification.
This way, if someone purchases keys with a stolen card and tries to sell them on G2A, there will be a paper trail that can be followed. This makes it hard for repeat thieves to continue selling keys purchased with stolen cards, as they'll eventually be caught out and G2A could then potentially refer that personal information to the authorities.
As PCG has it, G2A has also recently launched a developer support program, to make it easier for game makers to block unauthorised key sales. G2A is now working with Microsoft too to help identify keys.
So far it has managed to block 550 keys which might otherwise have allowed gameplay through illegal key purchases.
Do you guys use sites like G2A? Or do you stick to buying straight from Steam and GoG?
