"Pizzagate" is a conspiracy theory that went viral during the 2016 United States presidential election cycle, falsely claiming that the New York City Police Department (NYPD) had discovered a pedophilia ring linked to members of the Democratic Party while searching through Anthony Weiner's emails. It has been extensively discredited by a wide range of organizations, including the Washington, D.C. police.

Reddit is an American social news aggregation, content rating, and forum social network. Registered users submit content to the site such as links, text posts, images, and videos, which are then voted up or down by other members. Posts are organized by subject into user-created boards called "communities" or "subreddits". Submissions with more upvotes appear towards the top of their subreddit and, if they receive enough upvotes, ultimately on the site's front page. Reddit administrators moderate the communities. Moderation is also conducted by community-specific moderators, who are not Reddit employees. It is operated by Reddit, Inc., based in San Francisco.
