Triple parentheses

[1] The triple parentheses have since been used on social networking services such as Twitter by antisemites, alt-righters, neo-Nazis, and white nationalists as a signal to target Jews for harassment.

In a June 2016 article detailing the phenomenon, Mic also reported that an extension had been developed for the Google Chrome web browser known as "Coincidence Detector", which automatically places the triple parentheses around the names of individuals who "[have] been involved in certain political movements and media empires".

[14] Journalist Jay Hathaway wrote that most of dril's followers understood the tweet to be an ironic joke exploring the uncertain "etiquette around this very 2016 expression of bigotry ... Can a non-Jew apply the (((echoes))) to his own name[15][16][17] as a show of allyship?

[18] On June 3, 2016, following the publishing of the Mic article, Google pulled the Coincidence Detector extension from the Chrome Web Store, citing a violation of its policies prohibiting "promotions of hate or incitement of violence".

[11][5] In the wake of Google's removal of the extension, some Twitter users, including Jews and non-Jews, intentionally put triple parentheses around their usernames in an act of reappropriation or solidarity.

[20] Jonathan Weisman, an editor at The New York Times, included the triple parentheses in the title of his 2018 book release, (((Semitism))): Being Jewish in America in the Age of Trump.

[22] CEO Jonathan Greenblatt explained that the symbol was "the online equivalent of tagging a building with anti-Semitic graffiti or taunting someone verbally", and that the ADL was "working with our partners in the tech industry to investigate this phenomenon more deeply".
