-- If the issue is doxxing, which was occurring to some degree in sites with cross-membership with r/the_donald, then enhanced auto moderation is needed. The tools are out there.
-- If the issue is so-called "hate speech" then give users the ability to filter content they find distasteful.
-- If the issue is click-bait to offensive or illegal content, then again, there are ample techniques and 3rd party resources for warning about, reporting, filtering and discouraging user click-through.
What concerns me is that Gizmodo and Reddit can only think in terms of banning speech. Combined with the recent pile-on over "fake news", I worry that expression on the internet is vulnerable to shill pollution, coercion and overly zealous social equality advocacy.
The irony of not applying innovative technology to problems at Reddit is thick, almost suffocating.
