Thank you for the advice, as long as my vp is above 30% my upvote will exceed the dust threshold, if not I set dustsweeper to in/out to automatically upvote comments with an extra (prepaid) upvote worth $0.03 before 7 days, always ensuring the comment author gets paid and I get a curation reward. I put about 10 hive into dustsweeper every few months to keep it going and I delegated 100 HP to help it out. I've rescued a lot of hive by using this tool, both for me and to others.
