I had a discussion with some other stakeholders of Hive and we decided that denying rewards with this way allows curators to still push the post up and down for visibility reasons. It hasn't been used too often so we don't have a lot of crowd opinion on this yet, but it's open to debate if that is the best way.
In any case, I've tipped you a small amount as I appreciate the post anyway.
Thanks! I love my exotic plants - they keep the bugs down in my garden and they are so lively.
