It's true that Wikia is not in a position to offer legal advice to our users. It's also true that under the terms of the CC-BY-SA license, you own the copyright to your contributions. DMCA notices must come from the copyright holder, so they have to come from the author and not a third party like Wikia.

As far as providing better support for users dealing with the takedown process, I will take it under consideration.
