if you're not certain that you are allowed to post the content, do not post it on bluelight. if you don't own the copyright to content you wish to post, posting it without permission of the copyright holder might be a violation of the law. even posting it with a disclaimer doesn't necessarily protect you from infringing on the owner's copyright. if in doubt, probably better to not post than post.
if you feel it's valuable, you can always post a link.
