You genius, have you checked how much voting power @randowhale has? The bot is right now at around 55%, and naturally it'll keep depleting as it doles out more votes. It's not the bot's fault that the percentage is falling - if you have an issue, either look for another bot or just wait until @randowhale's voting power is back to 100%
