Games platform Roblox is being investigated by the United States' Securities and Exchange Commission (SEC). 

That's according to Bloomberg, made this discovery after filing a Freedom of Information request into the company. The SEC hasn't said that the investigation is into in particular as doing sound would harm "the ongoing enforcement proceeding".

"We have confirmed with Division of Enforcement staff that there are responsive emails between Enforcement staff referencing Roblox and that these emails are a part of an active and ongoing investigation," an SEC spokesperson said.

It has been suggested that this investigation is related to allegations made by the now-defunct Hindenberg Research in November, including that it had misled investors about player numbers and hadn't done enough to protect children on its platform. 

“We totally reject the claims made in the report,” a Roblox spokesperson said when Hindenberg's research was first published. 

“The authors are, admittedly short sellers (and have an agenda irrespective of the substance of Roblox’s business model and results).”
