What a total cock-up!
Apart from diluting the long-standing Black and White area of image copyright and use in general, on Poser Forums, to a dirty Grey, Daz have also given any would be image thief a strong case of plausible deniability if caught.
All the culprit has to do is produce the first Scream Design Newsletter, deny he received further updates correcting the position and claim he was acting in good faith. Any judge is going to take this into account and punish Daz (and the ripped-off-artists they host) because they should have got it right in the first place and are responsible for confusing the poor picture-thief.
The lure of the fast mighty dollar makes fools of so many sensible people, to quote ancient Roman saying "festina lente" (hurry slowly).
