I'm of the firm opinion that, while a protocol-based social network would be the ideal, Twitter could still move to a more equitable method of content policing and still make profit: allow people to volunteer to moderate flagged tweets, and if some consensus is reached then the tweet(s) are overridden and can stay. While this might push the layer one step up, people trolling that system might be easier to find by, say, every so often giving dud examples that clearly and egregiously break rules such that those that mark "keep" can be checked to ensure the system isn't being abused.
