It's called the 'Coincidence Detector' and this Google Chrome plug-in can identify a person who is Jewish and others who are perceived as 'anti-white'.
The system works in the background while users browse the web, the plug-in encases the person's name with a set of three parentheses, so it looks like this: (((Fleishman))).
Neo-Nazis, anti-Semites and white nationalists have begun using the parentheses to identify and target Jews for harassment on blogs and major social media sites like Twitter.

One such attack took place on May 26 and was directed towards Jonathan Weisman, deputy editor at the New York Times' Washington bureau.
Mr Weisman said the message of abuse started as "Hello ((Weisman))" and it began after Weisman tweeted a Washington Post article about Donald Trump and racism.
@Rusted_Ovum Care to explain?

Weisman asked his harasser, @CyberTrump, to explain the symbol. "It's a dog whistle, fool," the user responded. "Belling the cat for my fellow goyim."
The Coincidence Detector plug-in has over 2,400 users and has been rated highly by those who have downloaded it from the Google Chrome store.
It has a database of names which is regularly updated and with the click of a button users can refresh the Coincidence Detector to make sure their list of 'anti-whites' is updated and reflects the most recent additions to the database.
The app has proven a hit with many — one Twitter user who downloaded the Coincidence Detector praised the app.
"With this tool you begin to see patterns, constant bias, a common theme," Twitter user @FamesBlond said. "You want it deny it, rationalize it, fine, but we see it constantly. And that plugin shows it."

In addition to this, if it is believed that any person who is pushing an 'anti-white' agenda has been excluded from receiving the (((echo))) around their name, the user can submit the name of the person to a centralized database that's controlled by the support team at the Coincidence Detector.
However, many users have expressed their deep concern at the app, calling it out as being an 'anti-semitic' system and demanding to remove it.
A user commented on the application's page that it was one of the most antisemitic extensions they had seen and urged Google to remove the "trash".
A Twitter user expressed their disgust, saying they could not wait to file this under those things that make the world worst just by existing, while another one tweeted:
Someone should feed "Coincidence Detector" with the names of Neo-Nazis.

However, many praised the controversial system, demanding that journalists from the Huffington post of Buzzfeed be added, especially if they are pushing an anti-white agenda.
Wow what a surprise, the (((media))) got coincidence detector removed from the Chrome store. #CoincidenceDetector

It appears the app has been removed from the Google Chrome store.
