Xincerely Please do not try to waive away any clauses with the argument that "they would never be used". They are there for a reason and if a profit-seeking company can make a profit by using those clauses they will. Ghost-writers are a real thing and have been used for a number of different series. Its not just "child ____". Novels have been stopped because they criticise the wrong people or are too "dark". This might sound crazy to some people, but it made sense to the powers that be, so imagine what other things could make sense to them.
Check out RABBITICOL's message just before yours. Particularly this section:
"And after you have read it and don't like any clauses, don't let anyone tell you nonsense along the lines of: Those are just there for XYZ reason and Webnovel doesn't enforce them, they have never enforced them... or they don't have the manpower to enforce them.
That reasoning is utter garbage. Unless they remove the clauses, always sign it with the assumption that they will enforce them on the earliest possible moment."
This is true for all contracts from any party, not just those from webnovel. The key message (to paraphrase Rabbitcol) is assume that any and all clauses will be enforced and, if you are fine with it, then the contract is fine. People have different desires and needs, what is a good/acceptable deal for one person does not necessarily make it so for another person. For example: some people their IP is their baby, while for others it is just another commodity that they are willing to sell for an acceptable price. A bottle of water for 1,000 dollars is crazy for most, but a good deal to a dehydrated person. Just don't try to package any old liquid and pretend its just water with a different meaningless "colour" and odour.
