Thanks, Vad_M ...
It's often a case that Stardock has been/is already aware of these warez sites, but acting upon their presence is not always straight-forward. Very often it is a language barrier [I tried Babelfish for Russia once....not the cleverest of translations....].
One 'enjoyable' [?, eh, Larry] episode is with an ISP that allegedly understands English, being based in the US.
When you are obliged to quote the ISP's TOU [Terms Of Use] BACK to their administrators and still get what can only be described as a temporary solution you know you are well and truly behind the Eight-Ball.
Stardock warez is one issue....that impacts on all the legitimate SD users/supporters, however often these sites also host people's skins - an issue of copyright/intellectual property rights that impacts even more directly upon the individual skinner.
Stardock does their bit to deal with the program warez/premium content, and in so doing often addresses individual skinners' issues as a bonus, however the Number One person equipped to deal with a skin's theft/redistribution is the artist himself, as he is the legitimate copyright holder.
Individuals need to apply pressure in these situations as well.
It is often argued that once a copyright holder [artist] is shown to be dismissive/indifferent of/to his property rights in one instance he cannot then later successfully claim them if he so feels the urge/whim.
Anyone finding his/her skins/artwork/property anywhere it should NOT be is obliged to actively declare/defend their rights....
