It's ok. Just hope to see this group more active again :)

Well, because I want people to have the option of using my stuff to make other things with, if they want to, without onerous restrictions.

I use the CC license for a couple reasons. One, it's the internet. People will take things, repost them, trace them, play with them, edit them, etc, whether they have permission or not. It happens. There's no denying it. I've had my artwork badly traced and reposted by someone else before, complete with great big "OMG do not steal!" text written across the trace (irony), and the "artist"'s signature in a huge flourish across the bottom. I also had it all removed from the gallery where it had been posted without a fuss, simply by making the website aware of my CC license and links to the original work. Now, if that person had left my own signature on it and credited me somewhere, that would have been fine. That's the only time I've ever had to take action against anyone for taking credit for my work.

I post my artwork CC because I want to share it. I would rather give my permission openly for other people to play with my art and let them get some enjoyment from it rather than feeling like they have to sneak around guiltily. I get a lot of joy from drawing. I like that other people can share that too. I know my work gets reposted without credit. My friends are in the habit of showing me when it pops up on other sites. I've never seen a point in making a big deal over it. Usually, reposts of my work from from my FA gallery, which means my username is part of the file name, so it's still generally identifiable that way. If anything, it serves as free advertisement for me. Since I don't distribute print-quality files, it's not like the resolution is good enough for anyone to make physical copies worth selling. It's just not worth getting worked up about. There's no way to control something once it's posted online. Why stress yourself out from trying?
