In a statement on Tuesday evening, Zakaria dismissed their initial report, saying none of the passages they had pointed to constituted plagiarism.
Zakaria's employers at CNN and the Washington Post also responded. The Post's editorial page editor Fred Hiatt called the charges "reckless" and stood by Zakaria.
In their post on Wednesday, the anonymous pair disputed Zakaria's rebuttal point-by-point and concluded with a warning that more is to come.
“'Reckless' is also a funny choice of words for someone who just assumed that this was all we had to post," they wrote, referencing Hiatt's statement supporting Zakaria.
"Our Bad Media will have more extensive examples of plagiarism by Fareed Zakaria later this week," they wrote.
