I've bolded the more interesting parts.

"We have recently removed a deviation [link] at the request of lawyers representing the Kellogg Corporation who are objecting to your unauthorized use of allegedly copyrighted materials owned by Kellogg.

Kellogg is following a procedure under the U.S. Copyright laws that permits it to make this request under limited circumstances. The procedure is referred to as a DMCA takedown notice.

You have the right to object to this removal. Part of that objection can take the form of a DMCA counter-notification. The dA copyright policy outlines this process. [link] however you may wish to consult with your own attorney before doing so. Submitting a counter-notification can result in Kellogg taking action against you directly.

More information on the subject is available here: [link]

You may also notice that we have removed your work and left other similar works alone. This is because we are responding to a specific notice from Kellogg about a specific deviation. We are not responding to a general request with respect to all uses of Kellogg’s trademarks or copyrighted content. If you have any questions please contact us here: [link]"

It was referencing an old piece of fan-art I had done. It was just a parody picture of the Dad figure getting revenge on the Daughter figure. I thought parody was protected under copyright laws, but I think the law states I'd have to change the colors at least (which I did not).

Its kind of funny. That was one of my most favorited/popular deviations... And it was in scraps too! I don't really understand what was so special about it; it wasn't MY favorite at all. I had to be only 14 when I drew that image.

I actually had been wanting to delete the thing because I hated the favoritism it got over my original works. The thing is, I'm not the kind of person to delete a deviation if someone favorited it. Just out of consideration for them.

But now Kellogg has personally noticed the popularity of the image, and personally taken action against me through the DeviantArt staff. I'm actually honored. Its pretty cool to be noticed at such a high level, without even trying too. It means that someone at the legal department noticed the image and its collective popularity warranted enough attention to have taken legal action against it. Or maybe even the original artist found the image! Pretty exciting.

I mean its not the usual user-submitted deviantArt takedown of an image. This is Kellogg contacting Devart on a business level!

In summation all I have to say is that I entirely agree with the decision made. I made the image with no intent to harm Kellogg's reputation or anything. It was just for fun and a few laughs. Laughs were had, but that time has now gone and passed.

They have every right to moderate their intellectual property, and I accept the take down as-is and will continue on with my life with no complaint.
