So there's no "Downvote list" that I know of? There's Hivewatchers blacklist, but you're not on it. https://spaminator.me/api/bl/all.txt While I couldn't care less, there are lots of folk on Hive who will get their arse in their hand if you mention STEEM, and that could trigger downvotes. Personally, I think it's the wrong attitude, but there you go.

If you're saying an account is regularly downvoting you, then there's something personal going on.
