in short, you can't share everything willy-nilly for free...
there is license/copyright on clothing, skins/textures, morphs, assets, music...
-it's easy enough to import "paid/licensed" clothing/skins/morphs from daz inside vam (for personal/private use only)
-some users share screenshots using those licensed content, including ported env.assets (also licensed)
-ocassionally some stuff ends up posted on hub, those are "risky" type of content & can be removed at any moment
