My question is about copyrights, and using third party content in a monetized web page. How would services like stumbleupon embed other webpages using iframes to their website, and make an income of them? Is there any legal aspect to this?
In other words, simply, is there any sentence a website needs to insert into their TOS or such disclaimers before embedding third party content to prevent any legal issues?
Thank you.
I haven't been able to find the website, but I don't think it's illegal, as long as you don't claim it's your own content or overuse it. I fact, you could do better by stating that the content is take from the link.
