That's not how the law is written. Section 230 of the Communications Decency Act was SPECIFICALLY written to allow providers of "interactive computer services" to moderate 3rd party content posted to their servers. This was to address the issue in the early 90s where online forms didn't moderate at all for fear of taking on liability. A situation of only draconian moderation or none at all will tend towards only draconian moderation since very few users want a truly unmoderated space like the more obscure chan sites. Its the worst of both worlds.
