RE: The Main Reason I (and my witness @l0k1 thereby) are Anti-Self-Voting
As yet I have tried to find a balance of such in the "self upvote" I have started to decline the "auto upvote" on my new posts. If I feel that a post has gotten unusually low attention, yet it is valuable, after at least 30 minutes I will usually upvote it and use "booster". I'm debating the ethics of this.
I have stopped upvoting my own comments. I upvote other's comments if I feel they are more useful than the ones above them in a comment chain.
I would be in full support of a comments earnings being 100% Power Up earnings. I feel this would be an excellent way to increase my investment in Steemit.
Personally, I want to see everyone on Steemit succeed. The catch 22 is that I would also like to see everyone on Steemit find their groove and post quality upvote worthy content.
I have trouble with the fact that you can buy influence on Steemit. As a fairly poor person who has to literally earn every penny, it is disparaging that a troll can drop a quick $5k-$10k into Steemit and instantly start making hundreds of dollars from their first self upvoted post.
There are two things I feel should be reputation based;
FLAGS
No one with a reputation under 45 should be able to flag a post. The reputation score means you consistently upvote good content and your content is consistently upvoted, therefore you know what the community values and you have demonstrated support of that value.UPVOTES
I understand that upvote values increase with mVEST. I feel that BOTH mVEST and reputation should be a factor in the value of an upvote. This would help to prevent upvote abusers from gaming the system by requiring high quality community participation to give high powered votes.

The effect of SP and Reputation are independent. This is the reason why this @dang007 despite having some million SP, can't put a ding in l0k1's 69.8 reputation score. I am not sure of the ratio, but it is probably logarithmic. Each extra number upwards takes 10 or 100x as many upvotes, from some amount of reputation score, to have an effect. In fact, when l0k1 downvotes an account with a low Rep like even as high as 50, it is similar in its result on reputation as a million SP is against anything.
The reputation score is on the chain, but it does not have an impact on anything except as a mechanism to enable an interface to suppress the appearance of posts, based on well respected, established accounts with high Reputation, or a sufficient cumulative number of such accounts whose total score adds to an equivalent amount, as to SP, where l0k1's rep behaves towards the reputation of other accounts.
The first time @dang007 flagged one of my posts, one of our allies came in directly with an upvote to counter it. For the sake of interest, I wanted to see what would happen if for the second incident, nobody inside the #steem-coop, or even curious bystanders, brought the necessary counter. Sure enough, it came, and now the posts are even more visible for having flags, and still a substantial reward after some seriously fantastical downvotes on it. *Noticing it reappear, @dang007 has now removed, and then re-added a stronger flag to again bury the post. To do any real damage to my accounts, he will need to persuade a respected member of the community to flag my posts. For fun, I have posted a provocation about this:

I am not sure there is any problem that needs fixing, with the reputation system. I think it has demonstrated directly this last 24 hours how well it actually does work.
That's an amusing way to poke the bear LOL
My suggestion for using reputation the way I described was a way to prevent "buy a troll" tactics. Since reputation can't be bought (I think) , it helps to level the playing field a bit for new users who can't afford to buy voting power.
Yup, I have been talking with the good folk in #steem-coop and I realised that we should probably be campaigning to have flagging (rep smackdown) and downvote (reward smackdown) separated. Others have campaigned for this, but I believe that I have the operational strategy and tactics to make this happen faster. Being outrageously bold is the central pillar of my methodology, hence #steempunk
Yes, your reputation can be sold, by selling your account. But you can't buy it any other way.
