Checked on the Diablo reddit today and there are threads full of alt-right dickheads complaining about journalists and SJW nonsense, it dosent surprise me they're trying to hone in on people who might be susceptible to this kind of thing using the whole 'us vs them' mentality.
I use the Reddit Pro-Tools add-on or whatever in Chrome which flags users who post in certain groups that are known to be alt-right. There's a loooooot of people in various gaming subreddits that are flagged.
