Roblox’s credibility when it comes to keeping its playerbase of children safe has this week been called into question after the arrest of Arnold Castillo, a child predator.

Last week, Bloomberg shared a report titled Roblox’s Pedophile Problem which documented the case of Arnold “DoctorRofatnik” Castillo, owner of Sonic Eclipse Online. The report suggested Roblox has failed to protect the many children playing the game, with more details then included in a companion video on YouTube.
