There is no content to a shame storm. It is mindless by its very nature. It is indifferent to truth, even in cases where the truth could possibly be determined. Therefore, like the Ring, it cannot be used for good.
The solution, then, is not to try to make shame storms well targeted, but to make it so they happen as infrequently as possible. Editors should refuse to run stories that have no value except humiliation, and readers should refuse to click on them. It is, after all, the moral equivalent of contributing your rock to a public stoning. We should all develop a robust sense of what is and is not any of our business. Shame can be useful—and even necessary—but it is toxic unless a relationship exists between two people first. A Twitter mob is no more a basis for salutary shaming than an actual mob is for reasoned discussion. That would be true even if the shaming’s relics were not preserved forever by Google, making any kind of rehabilitation impossible.
“But let none of you suffer as a … meddler.” (1 Peter 4:15)
