Is it allowed to use exploits on his own expirionce to make better anticheats?

No you can’t, I made a topic like this a few days ago and everyone said you can’t, only way us to rest in studio, seems you can’t even do that in a place made only for that…

Totally not, and some peoples have method like me for a long time now, but it doesnt work if the exploit doesnt save Nil Instances (syn does)

IY is open sourced, just grab the repo and look through it
