Honestly, after reading Shy's and Sheldon's posts I would believe Sheldon.
The skin Sheldon designed has a copyright of DeuceAce on it but I am sure that wasn't designed for DeuceAce, as that is a poker site and the colours on that skin aren't really poker colours.
Sheldon probably copied the copyright text from another skin he designed and forgot to change the name for it.

And about copying the tabular data. After creating so many skins as Sheldon, you start to use templates for certain parts and that is completely normal.
