Triple parentheses, ((())), also referred to as an echo, are used online to denote a person or organization who is Jewish or supports Jewish
people and causes. They may also be used around a word like (((them))) or (((
people))) to refer to Jews as a whole, especially by antisemitic
people as a dog whistle or to avoid being flagged for hate speech.
Some Jewish people have reclaimed the symbol and put it in their bios or usernames, but it is most commonly used about Jewish people in a negative way, rather than by them.
