No flips for you!
Most ToS's are not legally enforceable within the United States. Same with most EULAs. That's why they include the part about refusal of service; they can just refuse service to you any further if you repeatedly cause a problem.
However, let's dig into this... grabbing relevant sections.
This just provides a definition of Services for later on. It's relevant so some of the parts coming up make some sense.
The document on the first page does not violate that. Next section.
Well... Under this section, if you read it right, then ZeniMax possibly owns the Skyrim supplement. Interesting. And if you read it another way, ZeniMax cannot take action against this product since it was not actually submitted to them or through one of their distribution methods. And a third way is that both are true, making this potentially ZeniMax property that ZeniMax can't touch. But they certainly are not liable for anything that happens with it.
Basically, the item on the first page needs to change their last page to have a proper copyright notice for Skyrim.
But at no point does the ToS actually come into play if this is not a copyright violation, just due to the fact it hamstrings itself on what it can enforce by limiting itself entirely to content submitted to ZeniMax or distributed through them or something they own. No mod is distributed in that manner, the Minecraft mods are not distributed in that manner, the very document in the first post is not distributed in that manner... In no case can there be a violation of the ToS cited simply because the ToS does not apply to this situation.
Now, whether or not it violates Skyrim's copyright is another matter. There's a good argument there. And a very good reason not to take risks like the OP does in the first place. Because he's risking massive monetary damages and jail time, not having his document taken down from some distribution service ZeniMax runs.
Well, while I disagree with your reading of the TOS, and the statement that it's not enforceable in the US (hint: companies generally don't write legal documents to protect themselves that don't work, you're just assuming the point is to stop stealing; it's not), you are correct that it has little to do with the document in the OP. I don't recall if anyone said it does, though; I certainly haven't made that point. So, when you brought up the TOS, I thought you were making a point about what that document actually covers rather than saying that it doesn't pertain to the OP document. It doesn't, but it's not toothless, either.
If you infringe on the rights set out in the TOS, they can use that to take both your money and the IP created. In fact, creating something using the IP covered under the TOS means that you're granting Zenimax a permanent and no-holds-barred license to use your created IP however they want. To that effect, the TOS has a lot of teeth -- you give up your ownership rights to Zenimax if you engage in using their services to create content. But that has absolutely nothing to do with the OP effort, so, yeah.
The OP is covered under copyright law, not the TOS for a service the OP didn't use to create the document. I am very confused as to why you've brought the TOS into the discussion to begin with.
