> The courts have not clarified the line between acceptable editing and the point at which you become the "information content provider." To the extent that your edits or comment change the meaning of the information, and the new meaning is defamatory, you may lose the protection of Section 230.
I'm not qualified to say what the limit is, I'm merely hoping to provide some background on how 230 came about and that it does have some form of limits.
What's particularly unclear to me is that if you have a site under active moderation which could even include editorializing some small percentage of the posts that are made, how does that impact the potential liability from posts which you don't editorialize.
So unless Trump's original tweet, or Twitter's fact check are defamatory or otherwise illegal, Twitter doesn't care.
> Do I lose Section 230 immunity if I edit the content? Courts have held that Section 230 prevents you from being held liable even if you exercise the usual prerogative of publishers to edit the material you publish. You may also delete entire posts. However, you may still be held responsible for information you provide in commentary or through editing. For example, if you edit the statement, "Fred is not a criminal" to remove the word "not," a court might find that you have sufficiently contributed to the content to take it as your own. Likewise, if you link to an article, but provide a defamatory comment with the link, you may not qualify for the immunity.
You may be held liable for the commentary you provide, but you are not liable for the content you provide commentary for, even if you choose to sometimes provide commentary.
