Hello there :-)
Please don't exaggerate, it's not that your blog is destroyed, those are just some downvotes because people - most likely - disagree on the rewards. It it's hivewatchers, talk to hivewatchers, there's no central authority on Hive.
As you can see on my post, I also got $95 downvote, and that's fine, people have their right to vote however they wish. With popular authors it's really tricky, because it might be tempting to just write more frequent with less effort if upvotes are coming regardless (which is not true, it's usually because you've earned reputation among voters).
That's one of the reasons I don't post more frequently, because I know that will likely get votes, as people are expecting that it's high quality content, and I'm not able to meet those standards every day. Or week. Or sometimes a month ;-)
