5. Other subreddits are warning that MarchAgainstTrump mods are linked to alt-right subreddits. Again no word from the mods at ETS

So what's the big deal? EnoughTrumpSpam is the most active anti-Trump subreddit at the moment with 77,000 subscribers after a year. But MarchAgainstTrump is catching up with 20,000 subscribers after just one month. In the past week with less than a third of subscribers MarchAgainstTrump popular posts get twice as many upvotes:

If and when MarchAgainstReddit passes EnoughTrumpSpam in popularity, that will mean the most active anti-Trump subreddit will be in the hands of pro-Trump mods with known links to alt-right subreddits. They have just a year and a half until the elections in 2018 so don't be surprised when by then there isn't an anti-Trump subreddit left.
