11 Year Old Wants to Post on Social Media

I have an 11 year old son that loves to play roblox and wants to post his videos of gameplay online. I think he's too young for that. But I'm hearing from other parents that they allow their kids (his peers) to steam online.

Any suggestions to maintain his anonymity and privacy while allowing him to stream online? Or should I just say no. When is an appropriate age if so?
