There are political entities which exist solely to provide an online presence for their clients. It's no different than "Russian trolls", except they're being paid by campaigns and committees instead of the KGB. It is my opinion that every comment, submission, and account operated by these organizations should bear a disclosure stating who is paying for them, just like every other paid public communication they might do.
Can you elaborate? Twitter doesn't allow paid political advertising and Facebook has a clear disclaimer at the top of every such ad.
