Background on the subreddit deletion
Citing its policy against posting the personal information of others, Reddit banned the /r/Pizzagate board from the site on November 23, 2016. source According to the page that was left, Reddit denounced Pizzagate as a "witch hunt". Displaced Reddit users soon moved to https://voat.co/v/pizzagate. The ban arguably boosted public interest in the Pizzagate controversy, a la the "Streisand effect".
Meanwhile, Reddit continued to keep boards like /r/PedoFriends, /r/jailbait, and /r/necroporn, (pedophile and necrophilia hubs) and ban other investigative boards, like /r/CitizenInvestigators.
During the 2016 election and even after, Correct the Record and supporters of Hillary Clinton were allowed to violate Reddit Terms of Service and harass users. source. There are many double-standards in place there it would seem.
Washington Post's foreknowledge
It should be mentioned that the cited Washington Post article used in the first source was first dated by Google on November 22, 2016, one day before the actual subreddit was taken down. The subreddit was taken down at around 1-2pm on the 23rd, so there's no conceivable way an article could possibly appear on the previous day. According to Google themselves:
Be sure that if your content is date driven, that the date of last revision is the first date that Google sees in the source.If there are any other dates prior to that, there's a strong chance that is the date Google is going to display in the Snippet.
The first date in the source for this article, however, is 11/23/2016. A plausible explanation for the date would be that the article was being drafted on November 22, and likely not publicly available until it was ultimately published on the 23rd which would hint some foreknowledge of the Washington Post in the Reddit takedown.
Voat user 1ew pointed out:
So the article was published at about the exact moment the subreddit was taken down. That means the author, Abby Ohlheiser, must have known before, and probably Reddit asked WaPo to have a story ready the moment the subreddit was taken down
the page source of the WaPo-article gives for the 'banned'-screenshot this information: "Screen-Shot-2016-11-23-at-11.29.37-AM".
Considering that the Washington Post would use Eastern Time, this would mean they also produced the screenshot several hours before the subreddit itself was actually removed.
