I apologize as I seem to have made myself unclear. I'm not disagreeing or saying these security measures aren't useful, I was just stating the fact that people can and do get through these systems and players in this case can detect them even when security measures can't.

To your point, as that $$0.01 makes a difference, VAC bans also make a difference by preventing kiddies from jumping back in with their purchased cheat program. That's great. However, there are 'whales' that don't care for the cost, and even though they're a small number they have an influential contribution to the negative experience these people can bring.

I'm not a security researcher or a developer so I don't know what security measures are ever in place or what the hackers do to get through. I mostly play lots of games and once-upon-a-time would dig up free (likely infected) cheat programs that got through anti-cheat and contributed to the cycle that's ongoing today.
