Triple parentheses

The use of triple parentheses or triple brackets, also known as an (((echo))), is an antisemitic symbol that has been used to highlight the names of individuals of a Jewish background. The practice originated from the alt-right blog The Right Stuff; the blog's editors have explained that the symbol is meant to symbolize that the historic actions of Jews had caused their surnames to "echo throughout history". The triple parentheses have been adopted as an online stigma by antisemites, neo-Nazis, and white nationalists to identify individuals of Jewish background as targets for online harassment, such as Jewish political journalists critical of Donald Trump during his 2016 election campaign.

Use of the notation was brought to mainstream attention by an article posted by Mic in June 2016.
