As with anything, if it is used as intended then there won’t be any issues. But unfortunately it is human nature to try to find ways to “beat the system.” I do think that @knircky has done a great job with it and it is a great idea to help drive traffic and help the little guys make some extra scratch as well. It may in time lead to a debate on whether it is fair or not much like the debate about the use of and existence of upvote and resteem bots, but that is far in the future. To be honest when I started with steemit I almost gave up because I was making such little progress. If I had something like @steem-bounty from the beginning it would have helped me grow alot quicker. As it is right now I have steemify set to notify me whenever a new bounty is placed so that I can contribute if I feel I have something worth saying on the topic. I am starting to build a very modest “daily income” that is comprised of author rewards, steem power delegation rewards, selling 10% of my votes, curation rewards, upvote rewards and steem-bounty rewards. Making a little bit everday helps me to be active every day which in turn helps me make a little bit every day and so on. Thanks for the post @fun2learn!
