1) Revenue solved: Allow limited paid ads after tweets from commercial accounts So, people who follow Starbucks, for example, would see paid Starbucks ads after Starbuck tweets, say 20% of the time. If you hate the ads, you can unfollow Starbucks. 2) Moderation/Cancelling solved: Allow Twitter users to sign-up/opt-out of content moderation "jury duty." You'd get "Does this Tweet lie or offend standards?" on flagged Tweets. If enough people say "yes", the tweet could be red-flagged, blocked or the Tweeter put on timeout, etc. 3) Faceless Ban Bots solved: Implement a content moderation "Court of Appeals" where a blocked/banned tweet or account could be appealed, again with Twitter users acting as jury. You'd at least get to know why something was banned and get a chance to appeal your case to fellow humans.
