Agreed, dealing with bots, fake accounts, troll farms, and the scums of the universe actually posting child abuse, revenge porn, or other such things, is a hard problem, especially at the scale of Twitter. Designing and deploying mechanism that are effective at preventing those and have zero false positives is very hard. Having humans in the loop at that scale is very hard. It's all a tricky balance. You can force people to have zero false positives but it's futile, in practice they still will. You can force them to manually verify each posts, but humans also have false positives, and this might come at a cost that Twitter can't afford. It's complicated. What's less complicated is running your own website where you can be your own moderator... I think an alternative is to give people some rights. Like establish a category of things that is always allowed. Then use the normal court system. Of course, it's a terribly slow and expensive appeal process, but also the best, and publicly funded. Similar to a case where you claim you've been refused access to a job or business because of a protected characteristic for example. You'd need to sue.
