Guests

A guest (September 26, 2008 - October 2, 2017) was a special user for players wishing to not use a ROBLOX account.[1] Guests were known as "The True Testers of ROBLOX" by the administrators. Either way, a guest was a user playing ROBLOX without an account. When a player hovers the mouse over a guest image when viewing game servers, the name will appear as "A Friendly Guest".

Many users create fake guest accounts (eg. Guest123, Guest_6010, etc.) and dress like guests. However, many people can identify if they are a guest or not, because users cannot leave spaces in their username. They can also be recognized since guest names do not have underscores, and all real guests have one to four digits in their username (e.g. Guest 789).

If a player joins a game but does not register or sign in, they are labeled as a guest by default. The guest's avatar is a Terror (Became Guest 666)

placeholder for players interested in a game and want to play it before creating an account. The placeholders are BillyBloxxer, BettyBloxxer and DefaultGuest. When guests play games that save data (like money), they will lose all their data when they leave.

ROBLOX stores a cookie on the user's computer that keeps their ID. Cookie editors are able to change a guest's ID number by changing the UserID in Guest Data.

From 2008 to 2014, guests were able to speak by using the proper Super Safe Chat words. With the removal of Super Safe Chat they aren't able to speak or hear, which means guests are unable to communicate with others, and they have to create an account to chat. Recently, they have been given the ability to see text chat, but still can't chat.

It is possible for scripts to ban all players and not guests from a game. However, this violates the terms and conditions, because it makes some players believe that ROBLOX is a bugged game.
