Sometimes I don't recognize what y'all are talking about, and I almost want to defend reddit, then I remember: I've long since adjusted my reddit to be virtually nothing but niche. My largest is ~320,000, but it's just a "Deals" reddit. I've got two at 150,000, both very focused. And it goes down from there.
I'd hardly know this was going on except /r/blog is essentially forced on to your reddit front page.
It's just like Usenet was... subscribe to politics.vitriol.hate.anger and rec.sports.flame, and yeah, you're gonna get idiots. Subscribe to comp.lang.niche_language, get almost nothing but signal. Times never really change.
But in the end, the result is the same.
Maybe one of the nice things about UseNet was that you could only be signed up for a forum that you explicitly looked for? That at least forces the trolls to go out of their way to interfere with general-interest sections, not just go after them out of laziness.
There is also something to be said for educating users on the effects of anonymity.
It's like saying that food in New York is awful because you reached into a trashcan and found a rancid bagel, but is awesome in Chicago because you looked up the nicest restaurant and spent $500 on a meal there.
There was a time when I would read a news subreddit and reminded myself that every headline should be understood exactly in reverse. I stopped doing that because it's hard to keep up the mental filter.
I think the problem is the https://en.wikipedia.org/wiki/Eternal_September - reddit is mostly made up of stupid and bored teenagers.
If anything might be a lesson on community design it might be to put up a few more "barriers" between subreddits and the general population and think about how to control interaction between them.

Of course a cynic would say that reddit is just a reflection of the society we live in and that might be right but it's also a reflection of the society we live in where there are few consequences to been a complete dick (I think if you could punch someone through a computer screen reddit might be a better place).
I've been on reddit >7 years and I'd love to say that it was 'better in the old days' but honestly I don't think it was I just think I've reached a point in my life where I don't feel the need to surround myself with that crap.
The top subs I read and/or post to are /r/asktransgender, /r/ainbow, /r/comicbooks, and /r/kamenrider. None of them would've benefited from taking part in any kind of blackout (the first two of those function as support groups and any blackout could seriously hurt someone who needs help, the third is a mid-sized fandom where people care more about talking about their hobby than staging a juvenile protest, and the fourth is an extremely niche fandom so small that nobody would notice a blackout).
It's safe - I know all the people we can still have arguments but they are well behaved ones.
With the exception of a few niche subreddits and the (few) incredibly moderated major subreddit's the whole place has become a negative pit with horses beaten so badly to death Findus put them in their lasagna.
Twitter often feels the same way as well (I'm pretty much at the unfollow as soon as someone acts like an idiot stage now).
Ironically the only social network I don't hate is Facebook and that's because I have about 20 people I consider true friends on there, all signal no noise.
