Emil Kozole created Seen, a font
that cleverly redacts certain words as you type—a clever automatic
ligature hack. It comes in three cuts, with varying degrees of
censorship.
Seen is a font that has a preloaded set of sensitive
“spook words” that the NSA and other agencies are using to scan through
our documents. The typeface can be used in any popular software such as
Illustrator, Indesign, Word or in a browser. It is used normally to
write text, but once one of the words on the “list” is written – the
font automatically crosses it out. Therefore giving you an overview of
your text and highlighting where you are potentially prone to being
surveilled. It gets its name by a Facebook action that happens when the
other user reads the message.
