Interesting thread…
I have never and will never scrape content, but I want to expand on a few points. Just want to say that I don’t agree with them, but this is the reality of the situation.
The first one is scraping a snippet from another site. I have asked a copyright lawyer friend of mine and apparently it is only copyright theft if a “substancial” part of the page is scraped. I am not sure about the definition of substancial and it will probably be argued in court, but he did say that 1 or 2 sentences does not amount to substantial.
Another point is that if somebody scrapes a SE, they don’t scrape your site. The SE shows your meta tags, which is really public property as this is what you want displayed on other websites. It will be VERY difficult to get a legal judgment against somebody scraping a SE.
I have been scraped as well and it is infuriating. We have to find a way to stop it, I just don’t know how (as the law is not really helping)!!
