Dear @codix, please do some research on how Steemit works before you post stuff like this. In order to make these bots work, they have to be loaded with SP. Which costs money or needs content. You can also just load your own account with 1250$ and upvote your own content. Or use upvote bots on Steemit. Steemit is still in beta and of course not every gap of abuse has been closed yet. Let's talk again in a year ;)
