I know people who have fully bypassed and reversed AAC. One day, they might even release the full source code, but for now, they’re still making money off it. I won’t name anyone, but it’s clear that there aren’t any truly solid anticheats for Lineage2. As I’ve said before, kernel level anticheats are the only real solution. Anything that runs as Internal and injects gets flagged, and your account ends up getting kicked or banned. That’s just how most games handle it nowadays.
To TL;DR the whole thing cheating will always exist because there are people out there smart enough to bypass any protection and run private cheats. Public cheats are always detected eventually, so I don’t see any point in buying AAC, especially when they claim it blocks adr, which simply isn’t true.
