Worth taking note that in today's climate, you really cannot win when you are in a position to moderate important things that a lot of people use. There is constantly tremendous pressure on you to perform opposing actions, and even making no decision at all will cause you significant mental stress and harassment, regardles of what the issue is.

Would something decentralized help? I don't think people want that. The_Donald involved a lot of spreading their message / fake news sites / spamming across other subs and etc. Do people want to be on a platform where other folks on the same platform are targeting their community with dishonest and often bigoted content?

Yea, I gotta say, having to previously deal with r/The_Donald brigades on another large subreddit was incredibly annoying and depressing.
Can't speak to spreading fake news, but massive influxes of r/The_Donald users spamming truly vile stuff in an ostensibly non-political sub really sucked (as a moderator, to clean up).
The only thing that works imo is fairly strict moderation, or extremely niche/small communities. Everything else just gets swamped by toxicity. Decentralized vs centralized isn't really the right dimension to look at I think.
And as soon as your small community grows... the trolls come a-knocking.
