Imagine being an evil dictator, who just got to power after years of trying... what's the easiest way to find your strongest opposition? Just buy data from social networks.
I mean... look at some stuck up countries with a lot of religious nuts, and some data, that you either bought a butt plug, googled a butt plug, went to an online buttplug store or worse... and it's just a bit of plastic.
Notice how those two examples aren't restricted.
> Sites like facebook can sell your interests, google can sell them your search topics, etc.
Governments don't care for that kind of data, that's why they willing to restrict those. Even though the best reason to use Google, is because they know my previous search topics and what I clicked on.
I imagine Google filters the bad stuff, so you're not likely to actually see anything life scarring with that first search. But go ahead and run the experiment and see if anything comes of it.
