The only question NOT ASKED in this thread is the following: Were you using Chrome or Firefox in sync mode? I experience this result ONLY after I got my Firefox browser synced all over my computers, the cookies gets synced between the pc's and so you get that result.
And how is that EVEN A SECURITY BREACH?
Also, why the hell are you hiding from, why DDG, I use BING on my phone and Google on my pc's and tablets, and I love it how they analyze all my activity and makes my searches even more relevant.
Are you somehow 12 and hope your mommies don't find out about your little porn secrets?
