The problem of disinformation through social media is enormous but little is done to combat it, also because it is a headache of extreme complexity. Managing billions of contents and distinguishing the true from the false is something that goes beyond any automatism, which is why the giants of the web have been working for years to understand how to deal with the issue.
Small steps are always better than nothing: in these days Instagram (source Engadget) puts a new functionality for US users, with which it is possible to reporter false news. In the settings, those that are accessed by touching the three vertical dots, you can now report a content as “inappropriate” and then specified “false information”. What happens then? The source isn’t clear: we know that if the report proves to be founded, the post will not be removed but will lose a lot of visibility. The creator of the offending post will not be notified.
