I applaud you for doing that... my voting and curation remains 100% manual, which sadly means there are sometimes some great content creators I don't get around to, all the time. But I just believe that a *social* content site is about people, not about automation. Now, if everyone used an upvote bot with as much discernment as you, maybe we wouldn't have issues... I'd like to think so. 

The other thing I try to make a point of doing is to *curate my own content.* Since I create a lot of posts around the idea of "engagement and interaction" it would make no sense for me to not come back and respond to interaction. Whether that "earns rewards," or not. Engagement is a two-way street...
