I did make a guide on anti-cheat and how to actually prevent exploiters it is linked here: How To Prevent Exploiters / Cheaters Properly this is just a guide for the developers that want to add a system like this in their game. Also, It doesn’t really hurt to add extra security. Account age systems have prevented exploiters in games before like Dahood. Yes, I know you are going to say Dahood has many hackers and it does the only real way to fully rid exploiters is to have a mod team and a good anti-cheat that is server sided. But an account age system can prevent some hackers that have new alt accounts. In the end, the developer is at choice to add an account age system or not.
