I think there are a couple of issues there. One is whether we're talking about illegal content to the extent to which you have legislated to render this kind of content illegal, and it sustains a potential Charter challenge, then you're okay on that front.
Bear in mind that you switched quickly to say it's a Facebook ad. Oftentimes what we are talking about here within this context, though, isn't necessarily the advertising that Facebook might be profiting from, but rather the third party content that is posted by users. That's where a lot of the attention has to be focused.
