Consider Steemit
So, as it turned out few campaign participants can prove their authorship.
Especially for managers and participants demanding justice!
There is such a program, called eSteem Surfer, in the latest update there is an opportunity to pull out the chronology of changes.
So I suggest in the debate on the attribution of primary use information, such as through eSteem Surfer.
