I think you’re missing the point of why they’re buying cheap game keys. In fact, it sounds like you think a ‘ban’ is something bad to these players or will stop them. If it did, I’d probably be enjoying Rust still.
Not even VAC bans are perfect, although it typically stops the poor unfortunate kids who truly don’t know better at least.
Minecraft anticheat won’t be perfect either. It is a necessary and functional safe guard as is usually the case with anticheat (minus rootkits, fuck those useless tools), but people will always slip through. Note what other people in this thread are saying.
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.
