Buming can vote for about two of your posts per week.
You can safely use the booster for a couple of days by sending it your bets. They also do not always work, like this time (here you were even lucky, Boomer was able to come :)
After that, it's better to wait a while and publish cool posts with the hope of Buming. This is a kind of game :)
Your posts are very good :)
