Bing
From Wikicliki
I know. You're thinking, who on earth uses Bing? Some who's accidentally bought a windows laptop for the first time and had to use Bing to find Google so they could reset their browser's default search to Google? Oh wait that was me five minutes ago.
Turns out that Bing is great for Programming and Porn. And probably pirated materials too.
In Singapore SafeSearch is turned on. I switched region to UK and then it was alright.
So next time someone asks you who uses Bing? Its PROGRAMMERS AND PORN USERS! :-D
