There were about 4.2 million anti-Semitic tweets posted on Twitter last year, according to a new report.
Its weekly counts range from a high of 181,700 anti-Semitic tweets to a low of 36,800 tweets, according to the nonprofit that calls itself “the world’s leading anti-hate organization.”
The report is the most comprehensive examination of anti-Semitism on the platform, the ADL said, although it did a similar review but used a smaller set of keywords in a report released in October 2016.
The October 2016 report found 2.6 million tweets containing frequently used anti-Semitic language on the platform from August 2015 to July 2016, largely directed toward Jewish journalists, according to an ADL news release commenting on today's report.
“That was equally alarming but in a different way,” ADL director and CEO Jonathan Greenblatt told ABC News today.
“We are an open platform and hold a mirror up to human behaviors, both the good and the bad,” the company said in a statement to The Associated Press. “Everyone has a part to play in building a more compassionate and empathetic society, including Twitter.”
While the number of weekly tweets appeared to gradually increase over the 52 weeks reviewed, there were certain weeks that stood out as having significant increases. The ADL noted that it could not specify reasons for any increases over the course of the year.
Of the three weeks with the highest number of anti-Semitic tweets, only the week with the most appeared to have a discernable connection to a world event, according to the ADL analysis.
The next two highest weeks -- in mid-November 2017 and late-January 2018 -- could not be tied to any specific news event.
“Some moments were catalyzed by world events but most of it is just an increase in volume of venom,” the ADL’s Greenblatt told ABC News. “[It's] the new normal.”
Some of the demonstrators at a white nationalist rally in Charlottesville, Virginia, were chanting racist slogans and propagating anti-Semitic views when they took to the streets in August but, according to the ADL report, the week after that deadly event only registered as one of the 13th busiest weeks in terms of anti-Semitic tweets.
The week of August 13-19 had the highest number of possible anti-Semitic tweets but the smallest percentage of tweets that were actually anti-Semitic, according to the report.
Among the reasons for the gap was that much of the tweeting about the rally noted the anti-Semitism on display but the tweets were not espousing anti-Semitic beliefs themselves, and therefore were not counted in the study, the ADL said.
There was a range of content that the report authors were looking for, including tweets that drew upon what they call "classic anti-Semitic stereotypes," including Jews being greedy or controlling banks and the media and government.
They were examples of “how old and awful and disproven ideas have new and real traction online,” Greenblatt said.
“These things are right out of the Nazi playbook. These are hateful myths that were disproven generations ago but have somehow … gained new ground thanks to new media.”
Weinstein has denied all sexual harassment and abuse allegations against him.
The pro-Trump "QAnon" conspiracy theories, which some believe to be a secret leaker from inside the Trump administration, were connected to some anti-Semitic tweets as well, as were a number of references to globalists, which is a term the report said is used as a code word for "Jews" used by some anti-Semites.
