Username

A username is a unique string of characters which can be used to indentify a user on Roblox. Players can select a username of their choice upon creating an account, however after account creation the cost to change username becomes 1,000 Robux.

History
During the early stages of Roblox, usernames could have spaces in them, such as John Doe and Jane Doe, this feature was later removed in December 2006 due to users impersonating other users by using spaces.

In February 2016, underscores were added back into the allowed list of characters in usernames (the first time since they were initially removed back in 2006).

In 2018, users were prevented from having usernames made up of only numbers. This was to prevent users creating usernames of phone numbers and because Roblox were adding a login by phone number feature. Currently, Roblox usernames can consist of 3-20 characters using letters, numbers and a single underscore which must not be the first or last character of the username.

Changing Usernames
Originally, users were only allowed to change their names due to either privacy concerns (such as the username being a player's full name) or per request by the moderation team due to the name violating the ROBLOX Terms of Service. If a user did not provide an alternate name, the username would then be changed to [ Content Deleted NUMBER ] for usernames changed prior to 2014 or ResetUserID for names changed after 2014.

A feature released on October 22, 2013, allowed users to voluntarily change their usernames for a 1,000 Robux fee. All usernames that are changed must satisfy all username requirements and policies.

Namesniping
Namesniping is an activity people do to find rare or lucky names only earlier people could get. For example, "Player" is an example of a namesnipe. Most accounts are made for the purpose of taking the name before somebody else can; these accounts are often left inactive or rarely used.

December 2016 exploit


On December of 2016, there was an exploit where people could make a new account that was the same name a different user, "David " and "David" for example. and people also used this to make 2 letter accounts, such as "pi " and "hi ". This was patched days after the exploit was discovered and all users that were made with the exploit were deleted. At the same time, users were also able to create users with a dash in their name, e.g. Builder-Guy. All users with dashes in their name got reset.

Usernames with 21+ characters.
In Roblox, it is possible to have usernames with 21 or more letters using glitches. These usernames are mostly occurring in Xbox related profiles.

In 2011, an iOS glitch allowed people to to create accounts with a username consisting up to 50 characters. Many accounts with extremely long names have been created during that time, like this one.
