If you are celebrity and want people to follow you'll need to post your Npub somewhere that is verifiable like your website or something I'm highly doubtful/suspicious that Obama or RFK Jr is on #nostr

I don't just doubt those accounts, I know they are scams. Not even willing to give it a .0000000001% of being valid.
#[3] Please post your npub on your social media page. I was teaching a client about nostr and we were discussing this exact topic. How do we know it's really Jack Spirko? I told him no problem, we'll go to Jack's social media page and you can confirm his npub! Oops. We were able to search your web site and found your #grownostr episode and confirmed there, but it would be nice to have it on: https://www.thesurvivalpodcast.com/get-social
Maybe, but the RFK account had several people confirm it was him, including Jack. Someone posted an email they had requested the campaign confirm it's him and they responded (could be faked easily). None of this is as good as RFK himself posting on Twitter or his website about it, but given that the RFK nostr account hasn't done anything since that day I don't think it's something to worry about. If it were active I think that would be another story, but I could see him doing this at the request of a friend just to humor him and then forgetting about it.
As for Obama, I hadn't heard he was on here. That seems like a stretch, I wouldn't trust that one.
