Triple parentheses
From Conservapedia
Putting a name of a company or person in triple parentheses (((example))), is a way of singling out Jews used by anti-semites. It's also called a 'echo', and anti-Semites claim that it shows how Jews' actions 'echo' through time. There was an extension for Google Chrome called the 'Coincidence Detector' that put over 2,000 Jewish names in triple parentheses. It reached 2,500 downloads before being removed for hate speech.
Reclaiming of the symbol
Jewish people have attempted to reclaim the symbol by intentionally marking themselves with the symbol. In response, anti-Semites marked themselves with the symbol backwards to show their hatred for Jews, )))example(((.
