That was never in dispute, and I even addressed this. Though to expand on this, if you're a parent and legitimately concerned about your kids being engaged by adults in a sexual manner, then I would hope that you're much more concerned with any involvement they might have on social media. I assure you that Facebook, Twitter, TikTok, and Discord are infinitely more dangerous with regards to child predators than FF has or will ever be.
Do you have proof of this, because I don't see this to be the case at all from what has been previous communicated by SE. This also doesn't align with the way laws work in most jurisdictions, you need some form of reasonable proof communicated to SE for there to be any liability if they failed to act upon it. That said, those who engage in ERP should be mindful that someone they might engage in these activities with could be underage, in which case they could be opening themselves up to some serious real life legal repercussions.
Again though, none of this actually means that ERP is or should be banned from the game. As I previously stated, Yoshi P has addressed the issue and said that it's acceptable under certain circumstances.
