@busy.pay is one of Busy.org's upvote bots (along with @busy.org) which will give an upvote to a users blog post provided that he use both the Busy.org platform and the "busy" tag.
Based on Busy's code to get an upvote from the @busy.pay bot, one must have at least 1 Billion followers_mvest. If one has less than that then the vote will be coming from the smaller account @busy.org.
I actually have written a blog post about this from months ago and one that have been verified by the people behind Busy. So check this out:
It was from months ago, so it' s a little outdated. But the only thing that was changed was the Busy.pay's upvote is no longer calculated as:
followers_mvest/1Billion = upvote worth
But now as (followers_mvest/2)÷1Billion
It’s the account the @busy.org interface uses to reward its users who posted through the busy app and used the busy tag.
Busy has a “loyalty bot” of sorts and the main goal is to attract “influencers” and reward those. That means that the more followers you have with high SP (including what they may have delegated to other steemians/platforms), the higher your upvote from busy.pay will be.
But you only benefit that when posting through the busy.org site. And you need to use busy as one of your five tags - order doesn’t matter, doesn’t need to be the first tag.
Busy.pay is an account owned by @busy. It upvotes people who make a post on busy who have over a certain number of mvests following them and they use the tag busy as one of their tags while making a post.
Thank you for your question.
