There are two larger videos on Ben Swann's 'Reality Check' segment on Pizzagate that I have happened to come across. One is Ben Swann's own Youtube video, which supposedly has about 15k views, and there is another (channel David Dobbs) with about 100k views. The video Swann posted on his Facebook page currently has over 500,000 views and 20,000 shares.

If you search for Ben Swann Pizzagate on Youtube, only a handful of videos on the subject show up, with an average of about 2k views. Neither Ben Swann's own video or the David Dobbs video show up on Youtube search. Youtube has been caught repeatedly modifying view counts to make a movement seem insignificant and memory-holing/de-listing viral videos, and this appears to be another example.

As noted, CBS has also taken down Swann's video from their website 'our apologies, page is currently unavailable' (http://www.cbs46.com/clip/13036440/reality-check-is-pizzagate-fake-news)).

I encourage everyone to test this out to confirm whether it is happening with respect to Youtube.
