When could counterfeits be detected with a somewhat decent accuracy? Is it something that has been attempted? I checked out Facebook Marketplace a few times since the launch and and everytime I'm just overwhelmed by the sheer amount of better or worse counterfeits. On top of that I start getting notifications more counterfeits, for a short while I reported them but after a while it felt pointless and now I just ignore the marketplace tab.
