Flexburger
Josh, more commonly known by his alias Flexburger[1], was Daniel Larson's first manager. Flexburger heavily manipulated Daniel and was the cause of the May 6th incident. According to Flexburger, he was active with Daniel from June 2020 to November when he was cut off. After the disappearance, Daniel would make several videos about him.
Manipulation
Not only did Flexburger and potentially other managers manipulate Daniel into doing extremely degrading acts, such as the May 6th incident, but they also probably manipulated the followers of Daniel Larson. It is no secret that Daniel's accounts are constantly hacked and stolen, leading to the ability of making fake "liked videos" and Pinterest accounts. After liking videos of little kids, Flexburger would then allow the public to see "Daniel's" liked videos, making him look like a pedophile. [2] This is what lead to "the accusations" in the headphone era. This topic is pretty debated as to what was actually liked by Daniel himself but in the end, Daniel is a person with mental illness who has a much harder time distinguishing right from wrong, especially when it's your dream to be a singer and Flexburger is promising you that.
