Hi all! As promised, here is the proposed text of the newest version of the rules. The staff has gone through like eight drafts and literally thousands and thousands of matrix posts to get here, so please be kind. You can see @limeey's comment on the transparency post if you want more insight into how this sausage was made.
We are opening these rules to commentary from the community before they go into effect. To be clear, this isn't a vote, but we will take all community feedback into account and answer whatever questions we can before finalizing anything.
Please keep in mind that we are not Reddit, we do not have Reddit's resources, and safety and consent are our priorities.
I'll post the draft in two parts in two comments: The new sidebar, and the FAQ/clarifications page.
You ask good questions, but I'm afraid they're very hard to answer no matter what the admins themselves believe to be morally correct.
Most of what you refer to is essentially a copyright issue. Unless otherwise specified by the copyright holders/creators of a piece of work, you're not allowed to repost it. In most jurisdictions this is very straight forward. The problem is enforcement, obviously: how are you going to verify that every OP has the right to share the material they're sharing? Excluding OC, you'll find they probably don't. Really determining this is very time consuming at best and impossible at worst.
So I don't think it would make sense to have a strict "you can only post OC or content you have the rights to" because it's just not compatible with a platform like Lemmy (or Reddit, for that matter). And if enforcement is more or less of the table, you might as well not have such an explicit rule and only respond to complaints 🤷
