That statement doesn’t really make sense. Especially in this case, the website is a business and a store. A government definitely has the right to take legal action against a physical store operating within it’s jurisdiction, so why would the same not hold true for an electronic one?
Yeah the same conversations have occurred in my household. I think you made the right choice here. I’m a huge gamer myself and developer, not on Roblox. Usually if anything it’s me being the lenient one when it comes to games in our home, vice my wife. This is one that I did not allow from day 1 regardless of the age of the kid. It was apparent to be a bad apple to me from my initial looks at it, and has only proven that point over the years. I can’t imagine though how hard it is for most parents who are not entrenched in that industry to navigate decisions like that.
