Tails OS. I went to search what it was and read the Wikipedia article. Guess I'm on a watch-list now, cause of my dumb curiosity lol
From Wikipedia
In 2014 Das Erste reported that the NSA's XKeyscore surveillance system sets threat definitions for people who search for Tails using a search engine or visit the Tails website
Nice try NSA. I ain't clicking that link. Fool my curious ass once; shame on you. Fool me twice - well... you can't get fooled again
