If you don’t watch what your kids play, your kids will find something inappropriate to play. This isn’t just a Roblox problem. Not suggesting Roblox shouldn’t have better moderation (holy hell should they) but this isn’t unexpected. Should it be? Maybe. Could they realistically do it? Probably not without some serious vetting changes—changes that would make “experience makers” have to wait to get their games approved.
Lock down the accounts so they can’t see server chat or get messages from randoms. Only allow your (parent) account to add friends. Play with them. Be present, at least somewhat, when they play.
