The short seller noted that reported cases are just the “tip of the iceberg,” suggesting many child abuse cases related to Roblox go undetected by authorities and media.

Roblox stock dropped Tuesday after the short-seller Hindenburg Research accused the gaming platform of inflating user metrics and deceiving investors.

Roblox stock’s short interest rose by 2.6% during the past month, which means those new short sellers might create more buying pressure on the stock’s recovery.
