Not hacks, just skill.
This group is just an easy way for the Rust player community to quickly identify fellow professional grade players. If you've received an invite, it's because you've been deemed good enough to attain a "professional" or even "high tier" player status.

The group is constantly curated as to keep it free of cheaters, it is common to confuse high levels of skill and practice with cheats. If you have any concerns or hard evidence that a group member is cheating simply contact a group admin with it.

Membership is by moderator or admin invite only.
