Yes in this case it essentially requires clients to provide some way to easily label something as fake, and then for other clients to read the labels, make some decision probably based on follow graph on which labels to show or not. Maybe NIP-32 is enough, I need to look into it again, last time I checked it seemed a bit complex.
curation is great, but it should be opt in. people need to be aware that things are being screened for them otherwise it is censorship.
"Curation" by a third party is censorship. Curation can only done by oneself.
i think there is a difference when you opt in to curation knowing what to expect. like forums back in the day, you go to a reptile forum you expect pictures of lizards but not cats. nothing against cats, but a cat forum probably wouldn't expect lizards there either... and Moderators clean up the porn spam and the occasional political post that someone on a reptile forum might not care to see either. it's opt in curation, which is self censorship. you're willing to risk missing a nice cat pic, but because you chose this particular reptile forum, you're ok with it. see how some might look at it?
So you solve "the problem" of someone posting something that may be inaccurate, by letting other people mark their posts with tags that may also be inaccurate. Sounds like a great plan that surely will not backfire and will guarantee that minorities never get gangbanged by majorities.
