Okay, so basically I was on the creepypasta wikia and I wrote a great creepypasta. I was actually proud of my work. It took be about 3 hours to write. I was finishing up my work, and it was all said and done. It asked me for categories. So I added some. I added categories that were apprently not recognized? and then he deleted my story, and he blocked my IP address from the site so I could not talk to the other admins about this. It was a good pasta that took a lot of work, and I feel like he was abusing his power a bit. Please help me out if you can! Thank you! I should also note that I was given no warning to this, nor have I had any previous infractions with the staff on that wiki.
I have read on Wikipedia that Wikia publishes all user-provided text under copyleft licenses. To my knowledge this means that all text but on wikia is put in the public domain. I have told a friend an idea I had for a video game on his measagewall on Ohga Shrugs Wikia. Does this mean I put my idea in the public domain. Also if this is true dose this mean I can not draw a picture of the a main character of my video game idea and post on my deviant art page because deviant art gives the copy write to all art post on the site to the artist who made it.
First off, I wish to correct you on how Wikia licenses their text. Copyleft means that a work can be distributed freely, but that it MUST be distributed under the same license as the original publishing. In Wikia's case, they publish their texts under CC-BY-SA, which means that you are free to share and change any texts on here, however you must give attribution to the original and also use the same license. So no, Wikia does not do public domain. (Besides, as far as I know.
As well, I'd like to quell your fears about your idea. To my knowledge, Wikia cannot take control of your idea. The idea of copyright in general is that anything original that you create is yours. That means that you can distribute it under any license you wish, whether full-on copyright, Creative Commons, or public domain. I do wish to mention that by posting it to Wikia in a form, you have given Wikia, at minimum, the ability and legal permission to display your idea to others -- but don't fret, they can't claim it as their own! Actually, if Wikia tried to claim your idea as their own, it would be copyright infringement, which itself is illegal.
Basically, since the idea originated from you, you can do whatever you so desire with it and Wikia cannot take the idea from your hands. So don't worry.
...And even if laws did say that doing what you did would take the copyright off your hands, the Wikia team is not going to hit you with a lawsuit for creating art of the characters in your game.
(To anybody: If I'm wrong on any of these points, feel free to correct me. This is just off what I personally know.)
Wikia Staff generally do not intervene on local issues. If you have problems with a local admin, contact them on their Message Wall here on Community Central and try to work out something. If they don't feel receptive to your side of the story, you should probably just find another wiki to contribute. :)
Not all staff members check their message wall regularly. If you want a reply, send it to Special:Contact/general, and a member of staff will reply to you. However, most of the time, they don't interfere.
