Roblox is facing accusations that it lied to investors about the number of people who use the platform. In a report published on Tuesday, the investment firm Hindenburg Research claims Roblox is “consistently overstating the amount of people on its platform by 25 percent to 42 percent or more.

The research firm alleges that the videogame company has exaggerated user data and compromises child safety.

Hindenburg's Roblox short is causing the stock price to crash, with the company under fire for allegedly showing false user metrics.
