I can&#x27;t think of a reasonable way of blocking people with bad intentions from creating Twitter accounts. But there are other things they could do.<p>One approach would be to expand their verified user program to people like me (ie the proletariat) and then have an option to switch the blacklist model of blocking people to a whitelist model of showing only tweets from verified users.<p>Or they could make a whitelist based on people I follow or that friends follow (or friends-of-friends etc...).<p>Or maybe just get serious with analytics and sentiment analysis and don&#x27;t show me stuff that is likely a troll.
