So i was using external glow esp made by user "joona70".

I've compiled it with 5k junk code but after 1 match (implying i did not go blatant nor got into OW) volvo caught me.

Any information regarding my issue? If i did something wrong please tell. Thx in advance.

Junk code doesn't make cheat undetected. Valve read for string or somesh*t inside running process. If you want to make external ud try changing 60% of code or do external ur self.

Thank you for the clarification
