How GM ban you ?

Hi, i have a question for you guys !
How GMs ban you when you use hack ? They can see that you login with hack, or just through reports ? I got ban many accounts in this days even when i was not botting so i want some explanations on how they understand that someone use hacks.

Can someone answer ? ..

The system scan the metin2 program and analyse the hack!

Some players can record you when you are using the hack and use this evidence against you
