more the payment or delegation, the more will be the percentage of upvote that we will receive.

For the same reason, i believe it is monetarily more beneficial for users with huge SP. As the organic curation and content creation is concerned, it is harmful for platform .

Good Bots which are actually those who don't require any type of delegation or payment to upvote the posts. They do curation by judging the quality of the posts

Thanks for enlightening. They are like normal accounts in that context .

hard work in publishing high quality posts but they don't receive rewards as per expectations.

Yes that's correct . I also feel like that .

Good luck in this contest .
