In-game ban

An in-game ban is usually given to the affected user by an administrator of the place or server. Therefore, this forces the affected player to exit the game. There are few ways in-game administrators in places can ban players from entering, or remove players from the server. These can range from being kicked or being permanently banned from the game. However, players who are banned from a game may play other games, or re-enter (if the player is kicked or un-banned by the administrator). Also, players can only be kicked or banned from a server using an admin script.

Commands (used by place administrators)
Administrators in games have the power to remove players from their servers (as well as affect other players). They can use these commands to remove players who do not follow game rules or affecting the environment of a server, or prevent the player from talking. Place moderators, on the other hand cannot remove players. The bans only affect the player's access to the specific game. However, they can play any other game and use the ROBLOX website. In many cases, affected players will have to exit the ROBLOX Game Client, and are unable to play the game unless they rejoin the server. Players who get muted can still play, but cannot use the in-game chat until they are unmuted. When a player is banned or kicked from a game using a ban command in the admin script, they will get disconnected, and a red banner with a notice will appear on the screen.

In-game bans are not available without coding your own admin panel using the player:Kick function or installing a 3rd party script from the toolbox. Although these may be useful, sometimes they can be viruses so user discretion is advised.

Other ways players can be removed from places

 * Affected players are kicked or crashed from a server, which is locked before they can rejoin (and only one server is available).
 * Players are kicked or crashed, afterwards the server is shut down and/or the place is made inactive by the place owner before the player can reconnect to the game.
 * Sometimes, players have to be in a group to enter a place, even though it is unfair to guests.
 * Some places have filters to prevent guests from entering, even though filters like these are violating the ROBLOX Terms of Service.
 * If you have disciplinary action taken on your account while you are in a place, you can get removed or disconnected by ROBLOX staff if banned from the ROBLOX service.
 * If you lose your Internet connection while in-game, you will be removed automatically from the game as your game client stops receiving data. Make sure to check the Internet connection before you rejoin.
 * Some games also have auto ban and can automatically remove players who are caught exploiting the game or using exploits/glitches in-game.

Did you know?

 * Some places "ban" players by using permission levels (the player is not in the owner's friend list and the place is "friends only").
 * ROBLOX staff cannot ban you from a place, but ROBLOX staff are able to disconnect entire servers. In these cases, you may see "This game has shut down" or "You have been disconnected from the game" on a red banner.
 * Place owners may also disconnect entire servers by making the place inactive, or by shutting down a server from the website while people are inside the place. This would result in players being disconnected and seeing "This game has shut down" on their Game Client screen.
 * ROBLOX staff can also "ban" players from entering a place, by putting it Under Review if it violates Terms of Service, even if the place is inactive. The place cannot be opened by the owner until the place is deemed appropriate for ROBLOX.
 * Scammers can be auto-banned if there's an anti-scam script added (when scammers say "FREE ROBUX" then the scammer will be automatically muted forever and punished).
