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.

During the very early days of Roblox, both accounts were used by administrators and were used as NPCs. The NPCs were actually able to talk. John Doe was last online on March 18, 2016, at around 6:04 PM, while Jane Doe was last online on December 4, 2016, at around 2:39 PM. Before this, both accounts were last seen online on February 27, 2006, at around 3:06 PM (when Roblox officially left the alpha testing stage). Many Robloxians speculated that these accounts were accessed by password guessers.

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 called 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 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 clearing their friend's list.

John Doe had 9 friends on his list while Jane Doe had 3 because of a bug that cause 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 one-year anniversary of 'The John Doe Attack' myth by changing their Avatar to resemble John Doe and Jane Doe.

On September 2017 John Doe and Jane Doe 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. It is was mysterious that John Doe and Jane Doe had this because they have not been online since March earlier that year. (Roblox admins were online, clearing their friend list and updating their avatars.) You could have also saw that other old users had this too.

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

Somewhere in August 2018, John and Jane Doe's inventory received the hat Verified, Bonafide, Plaidafied for an unknown reason. It might be Roblox verifying the accounts to ensure hackers won't get in.
