Since there are a lot of cheaters this time, are team is still processing and will update this list accordingly.↵
↵
I would like to request [user:MikeMirzayanov,2024-07-12] and the [user:Gornak40,2024-07-12] to take actions on the cheaters as well people who are leaking the solutions.↵
↵
I would also request to take strict action on [user:kyakaregajanke,2024-07-12] who leaked the solutions on Youtube and provided the solutions in a drive link and telegram too.↵

Anyone with this code has just copied from here .↵
↵
↵
I have would like to thank the entire **Cheat Patrol** team for exposing them.↵
Special thanks to [user:Vladosiya,2024-07-12] for actively helping us in the server and taking actions on convicted cheaters↵
