I think the devs knows the permanen solutions to this bots problems, it is hard to stop bots activities but if the developers doesbn't want bots on their gaming websites, they can do it but I guess they also need it to manipulate the numbers of users, that is what some of them use to show their stats to other gaming competitors, they can announced and bost of having million user but if you check very well, the real users might not be up to 100k playing game and they will be the quick to cry that users are stealing rewards, they want users and bots but afraid of how the rewards are stolen by users.
You mean games' developers allow bots to exist on their platforms to boost the number of active players considerably, consequently generating positive propaganda for the game. That is indeed a possibility, but on the other hand, fake numbers are never a positive propaganda on long term, because at some point legit players will spot this happening and will start blaming the game and badmouthing it on the internet's circles.
That is what happened to some play-to-earn crypto games and that is a good reason why they failed. Maybe developers think they are being smart for allowing bots to exist until certain point, but in fact, they are being foolish for killing the game created by themselves...
