Triple parentheses, also known as an (((echo))), are a symbol used to highlight the names of individuals of a Jewish background. The practice originated from the far-right blog The Right Stuff; the blog's editors have explained that the symbol is meant to symbolize that the historic actions of members of the Jewish faith had caused their surnames to "echo throughout history".[1] The triple parentheses have been adopted as an online stigma by anti-semites, neo-Nazis, and white nationalists to identify individuals of Jewish background as targets for online harassment, such as Jewish journalists critical of 2016 U.S. presidential election candidate Donald Trump.[2][3]
Use of the markup was brought to mainstream attention by an article posted by Mic in June 2016.[2] The reports also led Google to pull a browser extension meant to automatically place the "echo" markup around Jewish names on web pages,[2] and the markup being classified as a form of hate speech by the Anti-Defamation League.[3] In the wake of these actions, some users, including Jews and non-Jews, have intentionally placed their own names within triple parentheses as a sign of solidarity.[4]
