She only had a handful of followers.<p>But the way twitter works, one of your followers can retell the &quot;joke&quot; to all their friends, and they can tell it to all their friends. The system breaks down when they&#x27;re not sharing something they agree with, but something they think is so harmful that no-one (except all their followers) should ever have to see it.<p>If the joke is &quot;problematic&quot;, I&#x27;m not sure why sharing it isn&#x27;t also problematic.<p>Maybe a 140 character broadcast system is a good medium for a nuanced analysis of when jokes are funny (and a circuit breaker in a sometimes uncomfortable discussion) or so harmful that they can&#x27;t be justified, and where the line is.
