I'm fairly convinced that some of the Roblox controversy is a witch hunt. I have no knowledge of whether there have been legitimate issues, but the outcry I've seen on social media discussing Roblox and child safety often looks like a concocted story, and last month my social feeds were flooded with parents encouraging you to spread the word that Momo[0] is now spreading through Roblox and causing large groups of kids to kill themselves.
