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.
