Triple parentheses
Triple parentheses or triple brackets, in the singular also referred to as an echo (similarly called or stylized as, in both print and digital text, an (((echo)))), are terms for an antisemitic symbol and related orthotypographical convention that has been used by antisemites to highlight the names of individuals thought or claimed to be Jews, and the names of organizations thought or claimed to be owned by Jews, especially—though not exclusively—in communication in online spaces and forums such as popular social media and social networking apps, sites, and platforms, including as a form of doxxing or online harassment. This use of the symbol originated from the alt-right-affiliated, neo-Nazi blog The Right Stuff, whose editors said that the symbol refers to the historic actions of Jews which have caused their surnames to "echo throughout history".
