About indexing, if they make something available are they responsible if it ends up being scam related? Has that ever been tested in any Court?
When the authorities were busy chasing down so-called file sharing websites because movies and songs were being shared, they went after all of them but then left Google (because they owned Youtube) out of the picture when videos, music and movies all copyrighted were available for free on their platform.
I vaguely recall something about an investigation in to the material available on Youtube in the time of it being purchased and about lawsuits against Google but nothing happened partially because the corporations made deals with Google. I could have that wrong.
I remember when people were making the case that search engines and websites (especially Google/Youtube) that were allowing copyright material to be uploaded and linked should be shut down on the lines of pirate video websites therefore using the same analogy I understand why you said that. Google and other search engines allow any nonsense to be indexed and then shared without any fear yet the people who have probably become victims after finding scams and siphoning website directly from hyperlinks have no way to accuse them.
If only... I don't blame them for the indexing. The thing is that anyone can literally pay money to have a scam website linked at the top of the results. I can literally create bitcointalk100realnotscam.com and pay google so my website shows up at the top when someone googles for "bitcointalk".
