Like this question.
I want to know how copyright works. I do not want to break the law. However, if something can be done reasonably legally or with few legal consequences, I don't want to be left behind.
It's easier to express my idea by showing how others are doing it. Some says that I have to ask about my sites. Well, my sites are not made yet. I want to know whether it's legal or not before making it.
What about if I want to make another site like that site and want to follow the same strategy?
