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 March 2021 to August 2021 when he was cut off. After the disappearance, Daniel would make several videos about him.
Manipulation
Flexburger and potentially other managers manipulated Daniel into doing extremely degrading acts, such as the May 6th incident, over the course of a couple of months. He also manipulated Daniel into doing things like furthering his presidential campaign.
He also leaked Daniel's creepy Pinterest account and catfished him while pretending to be a minor.
Possible manipulation of the Daniel Larson community
Flexburger has been accused of not only manipulating Daniel Larson, but the community as well.
Flexburger leaked a Pinterest account of Daniel's, which was, to put it lightly, extremely creepy. It had collections, likes, and pins of little girls (especially Grace VanderWaal), age of consent maps, and other creepy videos.
This leak is controversial, however, as Flexburger, for a short period of time, was in control of Daniel's leaked Pinterest, as well as his other accounts. Many speculate that Flexburger was the one to like and pin the videos to label Daniel as a pedophile.
But these accusations of manipulation are sketchy at best. Flexburger only had the Pinterest account for a very short period, so short that it seems unlikely that Flex could've liked all that content in such a short amount of time. People also say that pins from 2019 debunked the leak, but Daniel could've simply just been recommended and liked old content.
Plus, even if the Pinterest account was fake, it does very little to counter the claim that Daniel is a pedophile, as Daniel is known to both have an obsession with Grace VanderWaal, an at the time underage (and still young) girl.
War and Doxxing
Daniel, in revenge for Flexburger exposing him, declared war on Flexburger. Flexburger was already an enemy of the r/Daniellarson subreddit, and with this new war surfacing, was doxxed and stopped communicating with Daniel in August of 2021.
