G2A still has a problem with sketchy game key resales, to the point where developers like Mike Rose have suggested that it would be better to pirate games instead. The site thinks it has a way to mitigate the problem, though. It's proposing a tool that would let verified developers block certain game keys from sale. They'd just have to paste the keys into a control panel to remove them from sale. In theory, this would prevent unscrupulous resellers from peddling keys they've obtained through bogus review requests and giveaways rigged using bots.
