One thing that has been proved in recent weeks, and I am thinking of the new owner of Twitter, is that it is easy to stick labels on forms of content or accounts.
We could legislate or make rules concerning online content. For example, regarding sharing an article on Facebook, it would be possible to show that it comes from a verified or approved source. Artificial intelligence is capable of creating categories of content. That is something to develop with the owners of sociodigital media. It would be one of the solutions.
I'm going to yield the floor to my colleagues so they can make other suggestions.
