This is unfortunately the case for all content moderation online. May it be Apple, Youtube, Facebook, or any other large platform. People only get to see the very small fraction that slips through, but have no clue about the immense amount of bad content that does get caught and removed quickly.

It's also worth noting that there's almost a game of natural selection going on, with these scams evolving and adapting constantly to slip through the automated systems. So it's a never ending war with no end in sight.
