John/Jane Doe

John Doe and Jane Doe are official test accounts created by Roblox CEO David Baszucki on June 25, 2005 (although their join dates are listed as February 27, 2006). The name John Doe refers to an anonymous male, and likewise, Jane Doe refers to an anonymous female. John Doe's user ID is #2, while Jane Doe's user ID is #3. They are famous for being mentioned in many different fake 'hacker' stories throughout Roblox's history and were mentioned in many clickbait videos.

Bot accounts
During the very early days of Roblox, both accounts were used by administrators as NPCs. The NPCs were functional by being able to communicate with others. John Doe was last online on September 8, 2017, at around 10:09 AM, while Jane Doe was last online on September 7, 2017, at around 8:11 PM (both according to Alexrocks911's Check A User's Last Online Information game). Before their last appearance online, John Doe was last online on March 18, 2016 while Jane Doe was last online on December 4, 2015. Before all of this information came to the public, both accounts were last seen online on February 27, 2006, at around 3:06 PM (when Roblox officially left the alpha testing stage). Many people speculated that these accounts were accessed by password guessers, but it was instead Roblox cleaning John and Jane Doe's friends lists.

Rumors & Mysteries
Despite not having logged on to Roblox since 2006, John Doe and Jane Doe possessed user badges that were created in 2012 and accepted friend requests from users who joined in 2008. CloneTrooper1019 created a video addressing how John Doe received badges from his place because of a bug in the Roblox client that allowed users to receive badges without playing a game.

A YouTuber named BADGRAPHIX also created a video explaining why John Doe was able to follow him. Like with the player badges, a bug in the Roblox web client allowed players to become friends with another player without them mutually agreeing to friendship (this bug has now been patched).

In around February 2017, several Robloxians such as Kazok, Equillex and more started a rumor saying that John Doe and Jane Doe would hack Roblox on March 18, and this rumor was frequently mentioned in some clickbait videos, which caused massive panic all over the game and site itself. It turned out to be false later. Roblox then had to explain the accounts in a blog post, and updated their appearance and cleaned their friend's lists.

John Doe had 9 friends on his list while Jane Doe had 3 because of a bug that caused TheC0mmunity, IhaxLV, CPUVirtualization, and Ananymoos to be some of their friends in September 2015. Many other users like erik.cassel, 1x1x1x1, Games, qa and BrownCheese had this bug too. John Doe and Jane Doe's friends were later removed in late March 2017.

On March 18, 2018, many Robloxians 'celebrated' the first anniversary of 'The John Doe Attack' myth by changing their Avatar to resemble John Doe and Jane Doe.

In September 2017, John and Jane Doe both obtained the Blade of Marmora Hood. To get the hood, you had to submit an entry of a robot using Roblox Studio. It was given to users in August 2017. At first, it was mysterious that John Doe and Jane Doe had this, as they had not been online since March earlier that year. However, it was later found that you could have submitted an entry to the contest entering somebody else's username, while you could still link your model. This was the reason many inactive users obtained it too.

For unknown reasons, John Doe's feed and description have been changed to [ Content Deleted ] in April 2017, likely a move by Roblox to convince players that the so-called 'hacker' has been dealt with.

Somewhere in August 2018, John and Jane Doe's inventories received the hat Verified, Bonafide, Plaidafied for an unknown reason. It might be Roblox verifying the accounts to ensure hackers or password guessers won't be able to access the account.
