I'm not really a programmer, just interested, but I'm a lawyer, so I can answer Your question this way:
1. the inability to copy content on the website is not an indication that content cannot be copied, if that resolves the resource itself;
2. if the site clearly States that copying of materials sarashina, the way it is and all sorts of replies on the fence too is written in the law is not working (but working in the kitchen with vodka:);
3. view the license documents if they're on the website, if it says that you cannot copy and paste, then copy, of course, impossible;
4. the situation is slightly simplified if the resource is implicitly said, for example, is prescribed in the licensing documents, but was not informed of this when entering the website;
5. if it's just predictions (especially in numbers), it is not subject to copyright, so no fines or sanctions may not follow the exception to the blocking of the site (very difficult to prove that You yourself did not invent these figures, and it took from the website;
6. if You have created a program that takes the content from the website automatically, the situation is slightly worse, because this is a computer program that may be intended to harm the interests of others.
