Just Wondering

If you make your own hack for a game, and don't let anyone else use it, are the chances high that vac will detect it or is it just completely random.

It depends on what the hack does. Memory editing is bound to get detected really fast, but it took VAC forever to detect the external hack. And even then, it didnt really detect what the hack was doing, just that the hack was running.

it really depends on how your hack works.
