A ban on ROBLOX is a result of an infringement of the Terms of Service, otherwise more commonly known as "breaking the rules." Because of the rather robust and dangerous nature of Off Topic, these bans are very common. All bans are given for a reason, but sometimes a moderator message is not provided. This leaves the user without any clue as to why they were banned.
Various slang or terminology referring to bans (often used to disguise talking about bans, of which is against the rules) is "b&" (pronounced exactly the same as "banned") or "#-dayer" (referring to bans only, with the number being the amount of days the user is banned for).
The only way to have a termination or ban lifted before the re-activation date is to send an appeal. The appeal system is often criticized for using canned (pre-written) responses, but the appeals are in fact read by real people. If the appeal reviewer does not believe the appealer was unfairly banned, the appeal will be denied. You cannot appeal the same account more than once, nor can you appeal an account that has been deleted for more than a month. Many users critizise the appeal system since appeals have a tiny slim chance of being accepted.
Types of Bans
There are several different ban levels on ROBLOX. All bans are varied lengths. Note that 1 day means exactly 24 hours, 3 days means 72 hours etc.
Essentially the same thing as a warning. These are very rarely given out but were common to new users.
These bans just log you out of your account and shows you what you did wrong. (That is if you did anything wrong) You can log back in straight away.
1 Day Ban
This ban locks your account for 1 day. There is no point appealing for a 1 day ban, since it takes around 2 days to reply to appeals.
3 Day Ban
This ban locks your account for 3 days. You can appeal for this ban but it often expires before ROBLOX support replies to appeals.
7 Day Ban
This ban locks your account for 7 days. It is worth appealing for these.
14 Day ban
This ban locks your account for 14 days. It is definitely worth appealing for these.
This deletes your account from ROBLOX forever. You can appeal for these, but only after a month of the ban taking place. Most likely, ROBLOX has some sort of backup data, which they delete after a month. You only get 1 chance to appeal, so make your appeal letter great or it's game over. People are also angry because of the fact appeals have an extremely slim chance of being accepted for deletions.
This ban deletes all accounts associated with the targeted user's email address.
Poison Ban Type II
This ban deletes all accounts in the IP affected by this ban.
This ban blocks your IP from ROBLOX. Trying to use a proxy to get into your account will result in an instant ban.
These replace all your forum posts with [ Content Deleted ]. These often, but not always, happen before a ban, and are common on the forums.
User Code 0x1
This disables you from playing any ROBLOX game on a certain IP. The length of this ban is unknown, some people have had it for months.
This ban is usually given out to players who have made sexually explicit places that have been considered adult content by moderators.
When the player tries to start up with this type of ban, they receive this error message:
"Roblox cannot startup. User code = 0x1"
Builders Club free of bans controversy
Some people have noticed that bans are less likely to occur when the user has Builder's Club, particularly annual OBC, the most expensive membership on ROBLOX. Some people even think that people with lifetime OBC can never get deleted, but this was proven false when an RTer with lifetime OBC was deleted.
When a person gets banned, sometimes they will end up going on the forums and complaining about it. If they get a Reminder/Warning, they'll sometimes end up posting about it on the forums, This is also a way to get banned as complaining about your moderation history is considered as a rule.
If they get a ban, they'll do the same thing but this time with an alt account. They'll say something like
"Wow just got banned for (Days here). Thanks mods."
Mods are idiots! They banned my account!
Mods are corrupt, account just got deleted.
Usually what happens is that when people make a thread, they get responses saying that complaining about your moderation history is a bannable offence. This will result in a ban.
In the ToS, it says that if you want to appriciate the moderation system you should post it in the S&I (Suggestions and Ideas) subforum.
