You don't, but you smile and just delete the content. And then you've done your part as a platform. You're very happy to delete things when notified, and you do it promptly. Then you get to publish a very factual transparency notice.

Someone will have archived the page already? Social media is upset when they hear that the big company tried to attack the small independent site to take down this page that They Don't Want You To See? That's out of your hands, you're a neutral platform and you've done your part.

You just need to fold immediately, and you're covered by all the safe harbor neutral platform protections. Same as forums, social media, any website with user-generated content.

Now that won't stop an asshole from suing you over frivolous nonsense. But it does make it easy to throw their suit away - like you said, if you have the spite and money to follow through with a defense.
