That's right. We can see them all more easily here.
And that's why I selected a relative newcomer like @newageinv with his comment to elaborate my reply. I bet 95% of all steemians would never think in join an autovote trail/guild if they did not earn even a cent from curation rewards through those 'blind automatic' practices while they were absent.
In fact, I believe that the vast majority wouldn't move a finger and would not have the motivation or will to waste time in it if it were not to get them some kind of financial benefit in return.
