Thanks for elaborating. The obvious flaw in this logic is that even the most original thing brings both the platform and the writer the visibility. Assuming you‘re knowledgeable and technically correct, this would always be unenforceable because it is the whole purpose of the platform to retweet, cite and repost.

I‘m not too knowledgeable in IP law or the local US court proceedings but where I live, your EULA/TOS become null and void if you put the customer at a disadvantage. Having this damocles sword dangling above their heads would most likely not hold in court (retweet = visibility but technically against TOS)
