The relevant part of the License is: "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made. You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use."
What this means, is that if you copy and reuse our original content (i.e., content written by editors and not by SM or any of their third-parties), you need to provide appropriate credit (more info about this can be found if you hover over the words on the license page, but what it boils down to is providing a link to the content, as well as attributing the creators (in this case the Bakugan Wiki), and info about the license.)
We did this to prevent what happened many times several years ago, which was that people would just directly copy our content and claim it as their own. I don't mean to antagonize anyone here, I just think it's a little unfair to simply copy and paste other people's work as if it's your own.
We obviously don't have a problem with you using material from SpinMaster and other resources, but when your articles are word-for-word what ours are, it's an issue.
If you would like to talk more about this, I'd be happy to chat, I just wanted everyone to have all the information when we're talking about this.
