Your question is more suitable for the owners of those sites not us. After all it isnt us who would be suing you in court. What we say has little to no impact.
Oh I totally get that, which is why I make sure any of the scraping I do isn't to make money, just to write about interesting analysis. But I'm just also curious about people here's opinions on legality and whether they care about following the specific site's rules.
Where I live, if there is no exchange of money for goods then there is not a contract. If there is fair use of the material, then copyright doesn't apply.
