There is actually a tool by a guy who has several tools but he doesn't want anyone using them I don't think. If i come across the link again I'll try to share. I used to use the tool but I think he doesn't want anyone using it but himself even though it is published and live. It seems like he just wanted people to go look at it for bragging rights...So Who Knows. I'm working on building some tools just for this but also working on building @steemthat into a one stop upvote bot.
So basically you could just send say $5 sbd to @steemthat and the bot will talk to all other upvote bots in its program and spread the money to them and then they will all upvote when their window closes. Working on it now but might take a while. When and if I can do it @steemthat will save you and a lot of new folks some time. The funds I raise now will help make this all possible for sure. We shall see. I'm an old coding slow turtle for sure.
