People will think this sounds crazy, but hear me out.
First, let's establish that I'm talking to you. If you are reading about blockchain ethics, you aren't spamming a thousand accounts. You are contributing whatever content it is that you contribute to the STEEM blockchain.
So what is it that you are contributing? Is it garbage? Do you know it's garbage? Then why are you posting it in the first place? So, of course, you think you are adding some kind of value. And if that's the case, you should curate it and reward it like you would any other piece of valuable content. You-as-author and you-as-curator are two different things.
And then there is the game-theoretic viewpoint. If you don't spend all your upvotes each day, then that means those spammers that are posting hot garbage are getting more from the rewards pool than they would otherwise. So if you don't spend your votes, you're actually rewarding the spam.
Do you find 10 pieces of content you want to upvote each day? Great! Upvote those. Are some of those your own? That's fine too!
I know, I know, I can hear the hypothetical what-ifs already.
Does this justify traf and haej posting 10x per day with maximum self-vote efficiency? If they actually believe that each piece of content is valuable and a real contribution to the environment, then yes. Is that the case? I dunno, ask them and see if you believe the answer.
