I, once, opened a case, asked LL about the copyright. They said they claimed only their logo. For other things ask the creators. I thought they think they are virtual world server. They don't take response in during resident arguments. But 'ask the creators'!?, I haven't planned to use their products or services ; mesh, texture, coding, etc, for commercial use. Just only the photos, mixed of thing, as picture, I took somewhere.
Anyways, thank you all.
