Beta_Alpha Just add an age requirement for multiplayer at this point. I'm pretty sure it isn't legal to let children under a certain age without use online services in most countries.
Well, actually the clause usually is "without parental supervision", but how are you enforcing it on a videogame?
We've pretty much done nothing about it because lazy parents used the internet to shut their kids up, and we just accepted that until it was too late.
We saw in the past that youtube suffered for exactly what you mentioned in the first paragraph and that lead to every content creator taking a bullet for their stupidity of not enforcing anything strict before, now Microsoft wants to avoid that huge lawsuit by implementing the required changes before they get it.
We either have the government grow a braincell or two and realise the PARENTS who let their kids use the internet unsupervised and then get into seeing some shit are responsible for child endangerment and neglect. But that will never happen because "OH NOOOO! BIG COMPANY BAD!!!". I don't fully blame companies for decisions like these, I blame the causes or circumstances more than anything.
