"For CC-BY-SA material, that means making sure that you have attributed the source of the content".if you don't do that, you breach the license and lose your rights to use it. Strangely this does not apply here until Wikia says it does, and even after it is deleted by staff they can redownload the content to get a new license.

I was told their is implied good faith, but there isn't, the license dismisses anything any additional implied terms (8e). The license allows for terms to be added or removed based on the jurisdiction it is sought be enforced in, and any of the possible thousands of contributors on a wiki can attempt to enforce it. The license applies to the work, and on wikis it is a collection, breaching the license for any of the items seems to me like it breaches the whole license.
