whether disclosure should be mandated, or already is mandated, these accounts were not hiding the fact that they were amazon representatives. disclosure was done.

so what exactly should be illegal? Companies interacting with people on social media? PR in general?

It is disclosed. They have their titles (Amazon FC Ambassador) the Amazon box logo and their names are all @Amazon*. It's completely transparent, which you'd know had you read the article rather than the title.

Don't mean to sound harsh, but the amount of comments on here from people that CLEARLY didn't read any of the article is astounding.
