Payola gone mad with Michael Bloomberg, Should those endorsing candidates hide that they have been paid by them?

From the Wall Street Journal:

Michael Bloomberg’s presidential campaign is hiring hundreds of workers in California to post regularly on their personal social-media accounts in support of the candidate and send text messages to their friends about him. . . . 

To staff the effort, the campaign is hiring more than 500 “deputy digital organizers” to work 20 to 30 hours a week and receive $2,500 a month, the documents show. Those workers are expected to promote Mr. Bloomberg weekly to everyone in their phones’ contacts by text message and make daily social-media posts supporting him, the documents show. . . .

The whole Payola scandal was that radio stations played songs without letting people know that they were being paid to run those songs. The irony is that the Democrats who pushed for banning Payola and yet they haven't attacked Bloomberg.
