The evidence is clear, unfortunately. People are just copy-pasting and swiping other content to make a quick follow. YouTube was supposed to be people (You) posting themselves on the web (Tube). Steem is supposed to be people... posting things about themselves. We have the same problem for the same reasons.
The problem on Steem is actually going to be more acute. Everyone sees immediately how much money is being made... YouTube is harder to make money on without a big following.
