Users on the Internet are starting to be afraid of googling and visiting websites that contains content like "terrorism".

After former CIA contractor Edward Snowden revealed the ubiquitous government surveillance of the internet, ordinary users worldwide drastically altered their web browsing habits, to avoid being prosecuted for visiting pages containing materials associated with issues of "terrorism."

According to Russian news agency, Sputnik, a survey by University of Toronto's Citizen Lab, Snowden revelations forced internet users to avoid websites with information about “al-Qaeda,” “jihad,” “Iraq,” or “nuclear enrichment.” Another research team got similar results last year, when they found out that Internet audiences seek to avoid such terms as “anthrax” or “dirty bomb” while using Google search.
