The following are additional thoughts to my earlier piece.
E-mail was the Wild West in the 1990s, without any non-repudiation regarding the authenticity of the sender of an e-mail. There was no simple way to confirm that an e-mail was sent from the e-mail address in the from field.
High-tech fixed that problem, for the most part, with spam filters and refusal/authorization lists (formerly known as blacklists/whitelists).
Now, social media faces a similar problem when people pass fiction as fact with harmful intent that violates laws, terms of service, security, etc. This is exceptionally easy and dangerous since these platforms amplify the content, especially using curated means (humans or algorithms).
What's the solution?
Social media needs to take on more publishing responsibilities like the classified ads in a newspaper. One way is by creating a third category in Section 230 other than publisher or service provider for platforms that amplify content.
It doesn't matter if it's hard to scale. High-tech needs to figure it out.
