I just had to add:
It implies the same thing as leaving your house unlocked when you go to the corner post office. You're taking a risk, and trusting that most members of the general population won't go in and take things. It doesn't make someone who might go in and take something any less liable. (Just a loose analogy - I've read enough times in this forum that copyright infringement and stealing aren't the same thing ;-) ) Are you saying that unless someone charges a membership for access to their site, anything they post is fair game?
Again, I'm not sure you're talking about the same thing as the OP. When you say "with facts," are you implying that you're using their facts in something you've written? If not, I don't understand why you specifically put "with facts" into the sentence. With attribution, there'd be nothing wrong with that. Facts can't be copyrighted - the copyright is on how the facts are expressed/presented. But I don't think that's what the OP is asking about.
