I dont know, but i would say give them a break but with that being said you kinda have to forget about being nice becuase they did steal a skin. Me myself being a skinner, I am very insulted when people not just use the skin without the proper permission but they take it farther and edit it for there own uses. And the most recent skin on the last of the first page looks like a old TZ skin but done in paint...
But anyways to some this up, Id say good luck and I hope you guys have learned something from this and wont go back to skin editing and if you actually try, you can make you own with photoshop or something of equal editing.
My 2 cents
