The Splinterlands logo is 100% owned by Splinterlands and I have never done any work on it - and even if I would have, it is the Splinterlands logo now owned by them. ;-)
Ironically, I am not a fan of copyright in any form. I do believe it is detrimental for a free society. So everyone mentioning me on HIVE for a post I did over two years ago, to comply with some imagined copyright I might have, which I don't own and don't want to own, is somewhat mind boggling.
I do appreciate the gesture, though. ;-)
