/u/hotnew11 is sharing videos from the YouTube channel News Today. The videos have eye-catching titles pertaining to politics, such as: "WHOA,WHOA…!!! Hillary'S Collusion With Russians Confirmed As Her Aide Flips On Live Tv"
News Today has 4,790 subscribers. The channel uploads about a dozen videos each day, and it's not unusual for a video to get 10,000+ views. The videos all seem to have the same format: A static image combined with voiceover commentary. Some of the audio clips are taken from Fox News shows (e.g. Tucker Carlson Tonight). I don't know who's creating these videos—there's a whole ecosystem of YouTube channels with similar formats. Some of the recent videos on News Today make references to events that occurred months ago, and there isn't a clear timeline.
My guess is that /u/hotnew11 is just a run-of-the-mill spammer, and that he's not part of some larger plot. I did find seven other Reddit accounts sharing links to News Today:
These accounts have been active in some of the tiny political subreddits, but so far their activity consists of spamming the same YouTube channel as /u/hotnew11. Here are the subreddits where they posted:

The vast majority of submissions only have 1 upvote, so I doubt Reddit is driving much traffic.
