A player who has left your Arma 3 server is no longer in the Online list. You can still ban them. The Seen lately card on the Players page lists everyone who played on the server in the last 90 days, newest first, and each one who is not banned has a Ban button.
The list shows while the server is stopped too, but a ban needs the server running with BattlEye on. BattlEye is the game’s anti-cheat.
Ban someone from Seen lately
- Open the Players tab.
- Find the card Seen lately. The number beside it is how many names it lists.
- Look for the player. The card shows the first 8. Choose Show all to see the rest, and Show fewer to fold the list again.
- Choose Ban on their row.

- Seen lately list
Someone who is already banned shows a Banned tag in this list, so there is nothing to ban again. Everyone else shows Ban.
The ban shows in the Bans card afterwards. To end it, choose Lift there. See unban a player.
How the list is made
BattlEye only knows who is connected now. So the panel looks at BattlEye’s list every two minutes while the server runs and remembers each name and GUID (BattlEye’s id for a player). It keeps them for 90 days and then forgets them.
This has two limits:
- A name that was never seen is not there. A player who joined and left between two checks may be missing. Use ban by GUID or Steam ID for them.
- Names older than 90 days are gone. Ban by GUID or Steam ID instead.
If nobody has played yet, the card says “Nobody else has played here lately.”
By hand
If you run the server yourself, BattlEye bans a GUID that is not connected with addBan. The time is in minutes, and no time or 0 is permanent:
addBan 0123456789abcdef0123456789abcdef 0 Griefing
That bans the made-up GUID for good. See BattlEye on the Bohemia wiki.
If it does not work
- The player is not in the list. See the limits above. Ask them for their Steam ID, or find their GUID. See find a player’s GUID.
- There is no Ban button. Your role may not allow moderating players.
- The page says the server is not running, or BattlEye is off. A ban needs BattlEye. Start the server and try again.
