The problem with such games exists as well but challenges are different:

- cheaters still have access to phished/hacked abandoned accounts that own the game that they can buy very cheap

- another way to get new accounts for cheap is to buy the games in countries where the games are cheaper i.e. argentina or turkey

- there is very little motivation from developers to completely stop the cheaters or slow them down (every banned account is a potential sale of new copy of the game) the developer benefits financially from cheaters continuing to evade bans

- the players hurt the most (who already bought the game and paid the developer) don't generate any new income to the developer and dont pose any risk to income generation unless they quit the game en masse (discouraging potential new players from buying the game)
