oh thank you for warning me. i honestly wanted to try some of ps4 games there. he has 144hz monitor, so Spiderman with ps5 power, and that monitor would have been fantastic view.
Ignore the FUD and just do it. I claimed them for a friend and my little brother who are on PS4, they are all PS4 games and they all work fine. You won't get banned, that happened to people who started selling the action of claiming those games a service and logged in over 50 accounts on their PS5.
