It's a tough thing to get on-board with, I fully feel ya. Yeah, the rewards pool has been super rapidly depleted due to so much of this self-feeding low content posting. If you flag these users, you essentially take their reward away and send it back to the pool for distribution. I'm just calling for people to not be afraid to use it sometimes. But if you use it, give reasoning as to why you chose to use the flag.
Thanks, man! Our designers are legit. We've been scheming up some stuff to get rolling for Steem (can't unveil yet!) and we've been tackling another DPOS/Graphene chain, Decent. We actually just got voted into an active witness position there. We've been trying to help people with technical stuff in that community as well. It's paying off :-). Hope all's well, man!
might I suggest following personz and his smackdown.kitty. They list and flag the most self upvoting users.. dang007 appears to be the biggest self upvoter. but he waits until day 6 to upvote most of his things it seems.. I flagged him once today. but his 157k SP is better than my 3k haha! But I will keep doing my part and trying. and as you suggest. I will leave a comment clearly stating why, and what he could do for me to remove it..
