In-experience ban

An in-experience ban is usually given to the affected user by an administrator/admin of the experience or server. Therefore, this forces the affected visitor to exit the game, if not, cannot rejoin. There are few ways in-experience administrators in places can ban users from entering, or remove visitors from the server. These can range from being kicked or being permanently banned from the experience. However, users who are banned from an experience may visit other experiences, or re-enter (if the user is kicked or un-banned by the administrators). Also, visitors are typically only kicked or banned from a server using an admin script, but some experiences (such as Work at a Pizza Place) allow visitors to be kicked/banned by popular vote automatically. Originally, notices about bans were given on banners in the center of the screen. Red banners were used until late 2018; however, a 'disconnected' notice with an option to leave is now shown when an in-experience ban is issued (except mutes, where the chat will disappear or "You have been muted" will appear with the chat bar disabled).

Commands (used by place administrators)
Administrators in experiences have the power to remove visitors from their servers (as well as affect other visitors). They can use these commands to remove visitors who do not follow experience rules/are affecting the environment of a server, or prevent the visitor from talking. Place moderators, on the other hand, cannot ban visitors; on some admin scripts, they may kick visitors. The bans only affect the user's access to the specific experience. They may visit any other experience and use the Roblox website. In many cases, affected users will have to exit the Roblox Player, and are unable to visit the experience unless they rejoin the server. Visitors who get muted can still visit, but cannot use the in-experience chat until they are unmuted. When a visitor is banned or kicked from an experience using a ban/kick command in the admin script, they will get disconnected and a notice with an option to leave will show up.

Some admin scripts, such as Kohl's Admin Infinite base the ability for place administrators to kick/ban visitors by admin level.

In-experience bans are not available without programming your own admin panel using the player:Kick function or installing a third-party script, typically from the Toolbox. Although these may be useful, some contain viruses, so user discretion is advised.

Automatic
An automatic ban occurs in cases where a script kicks or bans visitors for a violation of place rules or for violating Roblox Terms of Service. Examples include scamming, attempting to bypass the chat filter, spamming the chat repeatedly, or hacking. In addition, users may also be kicked by the server due to lag or connection issues. For example, in Ultimate Driving Westover Islands or other Ultimate Driving games, the game will auto ban you for doing things such as bypassing the chat filter, exploiting, etc. But other games can do this too.

Other ways users can be removed from places

 * Affected visitors are kicked or crashed from a server, which is locked before they can rejoin (and only one server is available).
 * Visitors are kicked or crashed, afterwards, the server is shut down and/or the place is made inactive by the place owner before the user can reconnect to the experience.
 * Standing idle for more than 20 minutes disconnects you from the server to not waste server space. Rejoining would bring you back to the experience.
 * Sometimes, users must be in a group to enter a place and will be barred entry if they aren't in the group.
 * If a friend of your account is in a group-only experience and you are not in the group, hovering over the user's account name will show "view details" replacing the usual "visit" button. This also happens if said friend is in a paid-access experience that you do not own.
 * Prior to the removal of guests, some experiences such as Super Nostalgia Zone had filters to prevent guests from entering, despite such filters being in violation of the Roblox Terms of Service.
 * If you receive any warnings, bans, or terminations on your account while you are in a place, you get removed or disconnected by Roblox immediately, and when the Roblox webpage is reloaded it will show the moderation message. However, this is the case only on desktop. Banned users have been seen in-experience on mobile.
 * If you lose your Internet connection while in-experience, you will be removed automatically as your Roblox client stops receiving data. Make sure to check your Internet connection before you rejoin.
 * Some experiences also have an auto-ban and can automatically remove visitors who are caught exploiting it or using exploits/glitches in-experience, such as Frappé or Clueless.
 * Some places "ban" users by using permission levels (the player is not a friend of the owner and the place is "friends only"). The same tactic is also used by some groups.
 * Roblox staff cannot ban you from a place, but they are able to disconnect entire servers. In these cases, you may see "This experience has shut down" or "You have been disconnected from the experience" on a grey error message in the center of your screen.
 * If you join a server and you have a low internet connection or Wi-Fi, then all other visitors will be frozen and turn gray before you are disconnected.
 * Place owners may also disconnect entire servers by making the place inactive, or by shutting down a server from the website while users are inside the place. This would result in visitors being disconnected and seeing "This experience has shut down" on their Roblox client screen; however, it has been replaced with "Developer has shut down the experience for maintenance". Furthermore, with an admin script, a place admin can shut down a place within the experience (a notice will appear) and disconnect the entire server.
 * Roblox staff can also prevent users 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 (for example, when scammers say "FREE ROBUX" then the scammers will be automatically permanently muted and punished).
 * Some admin scripts will allow place admins to "lock" a server. When a server is locked, non-admins that join the server will be automatically banned from the server until the server is unlocked. The non-admin will still be able to join other servers, provided those servers are not locked.
 * If a visitor is in an experience and joins another place through the same account on another device or tab, the player will be removed from the server, since one may only visit one experience at a time.
 * In some cases, users may be automatically banned from an experience due to conflict between groups and the user(s) wanting to join are in a group not welcomed in the experience. Normally, this happens on war groups' places but such bans have affected other groups when a sanction is issued against the group.
 * Roblox may revoke access to Spatial Voice Chat if a user uses VC to violate the Community Standards
