I have used it and it is pretty okay in my humble opinion. A strange thing that I saw was the fact that the bot received a pretty big upvote and I checked who has voted a bot so much, then I realized it was actually you :)) It is a good strategy to upvote its comments in order for it to gain visibility, what I would do is upvote them with a lower value not to become strange in case the posts have less rewards than the bot's comment :D

Eventually you can make daily automatic posts with the bot and upvote them in order to be able to promote it better. Hope you will see this comment and wish you the best!
