They could, but that would lead to players that actually paid complaining (to tinybuild, not reseller). Ubisoft did it, I don't remember it playing out very well for them. But I guess that's the only way to stop G2A and the likes from dealing stolen keys. And I don't think tinybuild would get money from keys "stolen" from resellers, but I might be wrong.
