Wall hacks are common. Even if I report them, they don't decrease.

I've been killed multiple times by wallhack players who have been sniping me with a sniper rifle from places that are clearly obscured by tree branches and leaves. I can't write the player's name here in Japanese because I'll get banned again, but could you please take some kind of action as soon as possible to reduce the number of people who casually use these types of cheats?

You still see recoilless cheats, recoil reduction cheats, and macro cheats. Unlike aimbots, these cheats don't guarantee victory, so don't leave them unattended.
