It's unlike Rockstar to use an anticheat system. They generally ban via reports or witness.It writes to local memory(RAM), to be more specific it probably uses WriteProcessMemory which accesses the game memory in real time and changes it, now if the game has some anti cheat which monitors memory then randomly changing values may trigger its anti cheat which may ban you.
