I am actually quite puzzled by what they choose to index now or not - for example, you'll find that a lot - but not all - of HN comment pages are not indexed or delisted.
So it really doesn't seem surprising to me that Google search can fairly easily be beaten nowadays.
EDIT: Well, in my quest for an example of a delisted HN comment page, which I have run into before, I found something even more curious: a page that does appear in the index if I search by title, but not if I search by some of the page contents (eg site:news.ycombinator.com my username and the word 'eliding') reflected in the Google cached version of the webpage.
EDIT2: I checked on DDG and searching on site:news.ycombinator.com for amezarak eliding does turn up the comment that Google can't find.
Except the internet was built to let us leech content from eachother.
If there would have been a capitalistic mindset behind it, I guess they would have started with taking your credit card number back in 1960.
This antisocial behaviour of walking in and taking whatever isn’t bolted down leads to an unfortunate arms race of watermarks, other technologies, and crappy laws that attempt to stop consumers from disrespecting the rights of producers.
Whether intended or not, Google at least makes you visit the website before taking the images. (Which is contrary to all the times google does this for its own benefit.)
The number of people who produce desirable content are drastically outnumbered by the number of consumers, so I’m very guarded about any rhetoric that fixates on consumer rights at the cost of producer rights. Naturally they don’t get an equal voice.
