Several pages on your wiki are in extreme violation of these principles. Being the owner and most active editor, I trust you know about which ones these are, but I'll give you a few that are mostly or entirely lifted from V&D without citations.
Just to clarify: FANDOM takes licensing very seriously. Every single page that is copied from another wiki needs to fulfill the attribution requirement. Failure to comply will result in me closing this wiki.
The list I posted is not exhaustive, and as the person responsible for uploading the content, I think you're also responsible for knowing what was copied. However, here's another set of articles that were mostly or entirely copied without citation.
All you need to do, at minimum, is say that the content was taken from Verse and Dimensions Wiki (providing links would help). Writing your own articles might be nice eventually if you want to truly develop something better, but that's just my opinion.
"Cheetah" (http://beyond-universe.wikia.com/wiki/User:Cheetahrock63) has no power over you, and all you need to do to prevent your wiki being closed is to take the articles with copied content (I have provided a large number) and mark them as having used content from Verse and Dimensions. Providing links to each page would be appreciated. If you want to rewrite things instead, that's totally fine.
You've just deleted the community support manager's message after editing it to include the text "I am so angry at you!".
I don't even know how to help you anymore. I'm trying my best, but... gosh.
Rewriting an article involves putting the concept you see there into your own words. How would you describe the ideas about astronomy and cosmology that you want to have on your wiki?
I don't know if you've gotten all of the content, but thank you for complying so far. I don't exactly have the time to search this whole wiki to see what's been copied, though. Stay on patrol, check to see what you've copied without permission, and then either cite it or rewrite it.
