'More than 2.5 billion messages are sent each day on Roblox'

"In 2021, approximately 2.5 billion chat messages were sent and 17 million friendships were made on Roblox daily.*

*Measured on active users on a representative, randomly selected day (12/20/21)"

Note - there is an inaccurate claim that more than 60 billion messages are sent each day on Roblox, made on a Bloomberg podcast - this claim is demonstrably false.
