I strongly disagree, although unfortunately I can't really propose a better solution. Filtering just enhances the echo chamber, it's true that social networks are proactive about it and "pre-filter" things but I think they're actually getting pretty good about it, they give the users what they want. And what we want is content that agrees with us, makes us feel right and confirms our biases. People effectively "filter" by selecting who they follow, what they subscribe to etc... Furthermore I don't think filtering "toxicity" on huge open communities can really work because most people out there are terrible at "not feeding the trolls". I've tried /ignoring trolls on IRC for instance, but then you're left with the messages of other people engaging the troll and it's somewhat even worse because you don't have the context. Then you try to block the people replying to the troll but then you have people replying to the people replying to the troll... Personally I feel it's mostly a non problem, I don't have twitter, I don't have a reddit account, I don't have facebook... I'm only active on smaller communities like HN. I think humans simply suck at behaving correctly in large crowds, especially anonymously online. There's no fixing reddit or facebook, they've just become the modern equivalent of scribbling a swastika on a bathroom stall. Cat gifs, pun threads, racist comments, it's the same thing really, instant gratification without any effort, just watch the karma go up or down. If you don't set any bar for acceptable content then you're bound to be overrun with low-effort content.
