This is an issue for me because I run loads of adult sites, google images burns my bandwidth to hell. I wish my images wouldn't show up in there, the traffic is crap. I can block google images but when i've done that in the past my site seems to take a hit.
dear now all search engine and social network not support to porn site and its harmfull content and you can add firewall on your pc.
Sex is one of the primary motivating factors for any kind of advancement, be it in science or technology and so it applies on the internet too. So may be google thinks exposing kids early on to everything porn will help them get the knowledge and make the judgements later on in life.
i think it is essentially due to the fact that google does not understand anything other than words, and its algorithms cannot understand an image.. can it? it makes a search safe by filtering images from websites with "un" safe words so that no "b(.)(.)bage" is displayed, but what if a perfectly normal site were t o show such a picture related to your search word? now how is it to tell from its website background this new sudden change? its more related with the mechanics of a search rather than anything else...
unfortunately this is an enormous industry and none of us or even governments could stop it. so as Ckabayan said , just turn on all the filters you got
