As highlighted by buzzfeed article on the dominance of fake news over real news in the last American election, or the the guardian paper on need it and Robert Mercer, it appears social platforms are at the moment not willing to be accountable for what they propagate as their main incentive is  how much some content can be viral.

Therfore, one could ask how to create an incentive to make them better control the quality of propagated information?

2 options seem available:

1) external incentive: create a legally binding status for all provider of information forcing them to check propagated information.

2) internal incentive
