The PlayStation Plus Collection is a group of 20 PS4 games given out to PS5 owners who are part of the PlayStation Plus subscription. The collection includes games such as Battlefield 1, God of War, Fallout 4, and others, making it a pretty nice deal for PS5 owners looking to bolster their assortment of games. It would also be a pretty nice deal for PS4 owners who did not own a PS5 and did not want to pay the money for these games. That motivation seems to be why some PS5 owners found a loophole in the system, which allowed any PS4 account to gain access to the 20 games being offered.
Thousands of PSN accounts have been banned, and according to community discussions, these accounts are concentrated in HK(@PlayStationHK ), and have in common the receipt of Sony's PS Collection service for PS Plus, which contains serveral PS4 games for free. pic.twitter.com/ECWPRgVuO2

In essence, PlayStation 5 owners could let another account sign into their PS5, so that account could get access to the 20 games through the PS Plus Collection. While this may not have been a big deal if it were just between friends and family, some users were charging others up to $8 to do a game transfer and profiting off the loophole.
Right now, Sony has not officially responded to any of the complaints about account bans or made any official statement about the loophole. For the banned accounts, it appears that PS4 users who bought the games got up to a 2-month ban, whereas some PS5 accounts that were selling the games have reportedly received permanent bans. Perhaps trying to cheat Sony is not the best way to get new games, as it could end up ruining your holiday gaming season.
