You're sounding like a kid...
Here's what happens...
Normal:
You hack in all the games you play, people know you do too. People threaten to report you, someone actually does report you. That person will need to include evidence in order to get the nexon staff to believe you're hacking.
Most members are too lazy to do this, feel it is pointless, they hack too, or they cant get the evidence.
Now:
With the GM games the nexon staff is trying to lure every member they can in. They know hackers will not stay away. They made these games specifically to lure in hackers/glitchers and instead of doing the whole reporting process they can just ban you right then and there.

Normal players report to the GMS...
that's like if you commited a crime and a normal person saw it and reported it, it would take time to go through and get you. If a cop saw you, then it wouldn't take as long.
(this is a bad analogie but you get it)
all the GMs have to do is press a button or to and you're banned.
ADVICE: Stay away from any GM game or turn off all noticeable hacks (no recoil, no spread, speed hack, etc...)
