On September 25, 2017, Denis launched the website Growbux. The website was exclusive to the mobile version of Roblox and was originally created so that users can get free robux by downloading apps. However, it instead would download potentially harmful applications onto any mobile device no matter what brand it came from.
The website was taken down just 4 hours after launch. On his Twitter account, Denis posted a tweet stating that he was "fixing the site" in order for it to comply with the ROBLOX Terms of Service, going against its policy on "free" robux, or giving away robux through a 3rd party application/site.
On October 19, 2017, Denis' Twitter account was deleted for an unknown reason, possibly due to his free Robux site, but was reactivated sometime later.
Although Denis is a kid-friendly YouTuber like many other Roblox YouTubers, lots of Robloxians dislike him due to him spreading false rumors about the March 18th, March 24th & June 30th hacks. Robloxians claim that Denis has ruined Roblox by bringing lots of kids into the game and overall ruining the community. He is also hated due to his aforementioned site, Growbux. A lot of Roblox developers and YouTubers have called out Denis for advertising his site for money, and for being a sellout. Another thing he is hated is for his massive amount of clickbait on his channel.
He is also getting hate for stealing titles and thumbnails from smaller YouTubers that also make Roblox videos, such as ZNac.This has caused people to dislike him.
When YouTuber ObliviousHD uploaded The Last Guest 4, a popular series which has now hit 8 Million Views, Denis commented "First" on the video. People have criticized him as this is a trick for getting subscribers or in other words; advertising.
In October 2017, Denis' Twitter account was suspended for seemingly no reason. The reason why is unknown and has yet to be found out. Users assume it was probably becuase of the whole Growbux situation but his Twitter Account was later restored.
Denis and 4 other YouTubers created a group called "The Pals" having 4 members including: Sketch, Sub, Alex, and Denis. Corl was formerly in The Pals, but got kicked out after a controversial series of tweets posted by him. They all owned a YouTube channel called "The Pals" and posted 3 or 4 YouTube videos a week.
