Please correct me if I'm wrong here.
Where you said:
"Authors are discouraged to auto upvoted their own post by this rule!"
As I understand it, an author receives 75% of the upvote.
The voter receives:
0% if upvoted in the first 15 mins.
50% if upvoted 15-30 mins later.
100% if after 30 mins
If the author auto upvotes themselves, don't they receive 100% of the upvote.
75% for authoring, then the rest because the voter (who is the same as the author) voted within the 1st 15 mins.
There are two types of rewards here! Authors and curation, when you author a post, you will definitly receives the authors rewards but you can receive also curation in your own post!
The reason why you are being discouraged is to give way to curators since you are sure to receive an author rewards.
And if, your not giving a way, you will get penalty withing 7 days and it will diminished your potential rewards about 25%+ on all potential rewards!
