So repeal Section 230 and require every site to manually evaluate all content uploaded for legality before doing anything with it? If it’s not reasonable to ask sites to do that, it’s not reasonable to ask FB to do the same for data you send them.

Your position seems to vary based on how big/sympathetic the company in question is, which is not very even-handed and implicitly recognizes the burden of this kind of ask.

Not before doing anything with it, just before processing it for specific business use cases like targeting.

Running a forumn is fine, and I don't care if someone inputs a fake SSN on a forumn post.

I DO care if someone inputs a fake SSN on a financial form I provided, and it is actually my responsibility to prevent that. That's what KYC is and more.
