Roblox has been slammed as a "hunting ground for child-sex predators" in a new lawsuit against the online gaming giant that alleges it caused the sexual exploitation of a 9-year-old boy.

Roblox shares slid more than 20% in early trading, as the gaming giant dialed back its forecasts for growth and first-quarter earnings showed player spending is slowing.

Hindenburg Research released a report on the gaming giant Roblox Corporation, alleging that the company has inflated its key metrics for Wall Street.
