Buyers who wish to tweak it can contact the Master and obtain a second 'unprotected' copy directly from him/her via email.
The Master 'marks' each version emailed out differently...in a way only he/she can determine [digital signing in the hidden bits of a Jpeg, etc].
The tweaker can tweak....
But if the tweaker also attempts to Pirate/distribute ... the version distributed can be traced to that person.
Then....that person gets a visit.
It sounds good BUT the hackers will still find it and just remove them.
the none hackers would be caught but, then the none hackres that know how to hide
their IP addres wouldn't...
and we know the Pirates are here..
Just follow my lead and Make crapy stuff that no one wants to download. Anti-Pirated .....
Oh, wait that would only work if you don't have the talent to make good skins WP, etc..
Some tips that might help
if your skin, WP, Etc. is on a Pirate site before it is uploaded here or on your other site(s) it's a good call that someone(s) that was helping you with it
(testing, making other skins, etc. off it) would be a Pirate of interest.
Upload your Art to one site at a time wait 2 to 5 days and check the Pirated site too see if it is there... if one is there day one and lets just say you sold 3
you know it has to be one of those 3.
it's just a thought.. I know it's out there, but is it..
