DarkRaven is correct, when admin witness the event we do what we can to stop it.
You can help by posting your documentation in the Ban Request forum.
For example:
Below is an example of UNSUNG_ONE making the same accusations about another player.

After my warning he stopped and left the server soon after.
If he would have continued, I would probably have warned him again. Since to me he was a new player. I try to give new players more warnings before severe action is taken. UNSUNG is not someone I have seen on the server before.
If he would have stayed in game things may have escalated to a kick.
Looking back at his chat log, UNSUNG accused a lot of players of hacking, probably everyone who killed him.
