Hi,
Obviously, you're free to post on this forum your report about cheaters, so they will be banned only on this server.
Or you post on my forum https://www.swat-bf42.org/ (edited the new address) and they will be banned on ALL the servers
On my forum, a team of players who comes from each community will spec the suspicious players quietly.
We will get some proofs and will publish it on each forum to ban them.
