Fleskhjerta joined Roblox on February 24, 2007. His first game was an obstacle course called fleskhjerta's i wanna be the super star (inspired by the infamous, devilishly difficult freeware game, I Wanna Be The Guy). In March 2007, Fleskhjerta uploaded his first Roblox video to YouTube. He began to rise into stardom and fame. Later on, he bought Builders Club and began to make places such as "Fleskhjerta's Blooper Studio". He started creating advertisements for his places and became wildly known for his places and name. His fame led him to become one of the very few original owners of the Domino Crown. In 2010, the YouTuber Jgoosse started a series called Fleskhjerta Re-birth. The series lasted for around 4 years and got Fleskhjerta more attention.
Fleshkjerta complained about users visiting every place he went to so they could ask if he could visit their place. He warned the stalkers that he would quit Roblox if they wouldn't stop sending him messages and donations. Later in 2008, he stopped accepting friend requests and communicated less with his fans because of these stalker issues.
TerminationOn October 4, 2008, Fleskhjerta was terminated after an unknown user reported 2 models with cylinder breasts he made in 2007 (with one rumored to be sexually explicit). Rumors say the user who reported him was Heroton2008 as Heroton's profile blurb reads "also, don't bother sending me a PM about fleskhjerta, it was over 3 years ago, get over it, and if you have something to say to me, say it to my face, otherwise I do not care."
On June 24, 2019, Fleskhjerta posted a YouTube comment giving additional information on why he was terminated from Roblox.
After he was terminated, he went back to making non-Roblox YouTube videos. A while back, Fleskhjerta tried to get the account unbanned so he could exchange his Roblox account for a Team Fortress 2 Hat. Fleskhjerta claimed the operator said this to his appeal. "Had you requested to revive the account earlier, we would've reopened it. But since it has gone over 7 years now... There's nothing that we can do about it. Sorry."
In 2017, Fleskhjerta made an April Fools video relating to Roblox. On October 20, 2019, Fleskhjerta confirmed that he would be making a video about Roblox after he reached 20,000 subscribers. On November 14, 2019, Fleskhjerta created a new account called Flaskherder, which he used to livestream himself playing Roblox games the following day. During the livestream, Fleskhjerta played CloneTrooper1019's Super Nostalgia Zone, Lumsden84's Survive The Evil Sponge Killer In Area Fifty None, ROLVe's Arsenal, and stickmasterluke's Natural Disaster Survival.
