I have nothing wrong with people selling porn, but it's not remotely kid appropriate. Society expects a large berth between the two. If a kids company hired a porn-star to sell their products that would be weird, even if they didn't mention porn while on the clock. Similarly it would be weird if Roblox was also a joint venture with PornHub. This wouldn't hold if they were just Orthodox Jews.
I'm taking the claim of "sharing porn on social media" at face value.
I have nothing against producing, sharing, and consuming pornography but its typically done in private. A social media persona is public. It is inappropriate to share pornography in public. When that public persona is attached to a place of responsibility, then doing so is showing poor judgement. It's not at all comparable to being an orthodox jew.
