By now, we all know that the NSA is spying on us. They read our emails, our texts, our Facebook posts, passwords, and they even listen to our phone calls. They record every thought we utter and every website we visit onto massive databases, and use sophisticated algorithms to predict our actions. But how exactly do they decide which of our thoughts are threatening, and which ones are harmless? Which words have the potential to flag us as terrorists? The answer may surprise you.

A Slovenian artist by the name of Emile Kozole has compiled a few of the words that international agencies use to identify terrorists. It’s a growing list that may include upwards of 40,000 words. He in turn used these words to create a font that crosses out everything you type that might be flagged by the NSA. He has since dubbed this, “Project Seen.” You can try out his font for yourself at projectseen.com, where you can also download it for your own personal use. You’d be shocked by some of the mundane words that can have you placed on some government watchlist.

Kozole explained his reasons for creating the font. “I still wanted to show and educate people on how ‘normal’ words we use in our online conversations on Facebook, emails, or search queries on Google are all stored and could potentially get you in trouble.” Perhaps such a font will make the public realize that the freedom and security of the internet is in jeopardy at the hands of the NSA.
