Thanks for the explanation @minnowbooster team. As a constant user of one of the best and profitable upvote bot in the platform I 'm really thankful for you guys. Though there are times that I can't buy larger vote due to how popular MB is. Though I did encounter a problem the yesterday. When I bought a vote directly from my MB account, I encountered an error where the bot just take my sbd but didn't upvote my post. I tried a few more times after that, three times in total with same result. Though the amount involved is small I still hope that this issue can be resolved. Thanks again and more success to you guys.
