As per my understanding. There should not be a single bid bot available on steemit. Every post will deserve a chance if these bid bots will not be available on the platform.
Due to non availability of bid bots authors will post good quality and unique content on steemit. Automatically article quality on steemit will increase slowly. Otherwise people with take the advantage of bots even it is a little profit.
I haven't used a bots service to upvote my content. As per me it is not ethical. And it also encourages me for writing quality content.
And if authors will post quality content on the platform then definitely other people will love it. And they will upvote there content. It will create a healthy competition and people will write good articles and bring quality content to steemit.
Due to this good quality content will be on trending page.
Self vote should not be allowed. There should not be an option to self vote their content.
This is as per my understanding only, i may be be wrong. Correct me if i am wrong.
