The correct answer to the question: Until 2015, each new Roblox user automatically had one friend. What was he called? would be, "Builderman".
Explanation:
Builderman is the avatar that represents the inactive account of Roblox creator David Baszucki and it was initiated in 2006. This character´s only task was to welcome new users into the Roblox system and engage them as a friend and then immediately initiate a program that is called "Followers", which was started around 2015. Initially, when the game was first created, this avatar´s name was "BuilderMan" and his physical appearance was different. After 2007 this changed, and then in 2015 he became known as Builderman. He welcomes the new palyers into the game, encourages them to seek friends, initiates them into "Followers" and then he presents himself as the CEO of Roblox.
