That's the best course of action, just point them to the information about him. I wouldn't go further than that, at least not to the channel host. Because here is the thing: Evans cannot really do much with this kind of exposure anymore. What happens if the interview goes well and people want to learn more about him? Ohhhhh. Whenever he rises to any level of prominence from now on, his past will be there, waiting to derail his hype train.
And also, the more people who want to learn about him, the more who find out who he really is, and the more time he will need to spend scrubbing his social media. In other words, the more attention he gets, the more negative attention he gets. And at some point, there won't be enough time to reply to it all or delete it all. This is your future, buddy. You earned it.
