Ruben Sim

Benjamin Robert Simon (born May 12, 1997), known online as Ruben Sim, is an American YouTuber known for his commentary and criticism of the online game platform Roblox. Simon began producing content about Roblox throughout the 2010s, building a large audience through satirical videos and investigative commentary. In November 2021, Roblox Corporation filed a $1.65 million federal lawsuit against Simon, alleging he had harassed other users and developers and posted tweets containing false terrorist threats that prompted the temporary lockdown of a Roblox developer conference. The litigation was settled out of court in January 2022, with Simon agreeing to a $150,000 monetary judgment without admitting wrongdoing, alongside accepting a legal permanent injunction banning him from the platform. Simon later publicly accused the corporation of using the lawsuit to silence his ongoing criticisms of their alleged child safety and moderation failures. Following the settlement, Simon shifted the focus of his channel to exposing online predators within the Roblox community. His investigations contributed to the FBI arrest of a prominent Roblox game developer and the creation of "Moderation for Dummies", an initiative to document explicit content on the Roblox platform. In 2025, Simon became a central figure in a broader community controversy after publicly defending and collaborating with YouTuber Schlep, a fellow creator banned by the corporation for conducting unauthorized sting operations against alleged predators on the platform.
