The Roblox ones are a bit of a minefield too.

I age restrict, block chat with everyone and monitor friend requests weekly. They are not allowed to play in their rooms.

Education is the biggest thing. They come to me if someone asks to be their friend. They don’t accept gifts from strangers and I explain that it’s the same as real world.

It’s a constant process that is always changing. Same as any other parenting job I suppose

Roblox is hostile to these controls - best not to even enter the ecosystem.
