This is not necessarily a good indicator, as a witch hunt on self-voting (and it would be a witch hunt) would prompt some to create other accounts, post their scat photos there to upvote, and then wash the money through an exchange and then back to their main account.

The other point of contention is that 17% seems like a random number. Maybe I'm looking at the 18% number beside my name and just wondering why it matters, but I believe these kinds of shame lists in a public place (especially on a blockchain platform where posts are permanent) are not the best way to go about sticking one's nose in everyone else's business. If Dan decided to create such a list and make it public on blocktrades blog or his website, I wouldn't have a problem as he is the one doling out delegated steem power and would probably do it in much better taste. But if you want to create a witch hunt, this is the best way to go about it, and it will not end well for the community as a whole.

Plus consider this, what percentage of my Steem Power is delegated and what percentage is mine? For me i own about 26% of my current total Steem Power, yet I'm on a shame list for upvoting myself ~18%. This is what I mean by witch hunt.

I believe the better approach is to put effort into finding obvious spam or plagiarized content, and flagging it. @cheetah and some whales already do us this service quite well. Maybe giving an option to flag something as spam that is separate from the general "flag" option, where it's quick and easy would suffice. An author would be notified (but not reveal who clicked the "this is spam" button), and they could dispute it. If the post was found not to be spam by a moderator if disputed, then whoever flagged the post as spam would lose reputation. This at least could stop the asshats from falsely flagging, while getting the community to work towards cleaning up all the spam.

Do I believe it's wrong to self upvote? no, or the option would not be there. Is it any of my business if someone out there is 100% self upvoting? never, and it is especially outside of ethical boundaries to post a shame list. Doing so should only be a last resort to target the worst offenders who litter the site with garbage and make an example of them. Making a public list like this is a sign of a malfunctioning conscience, especially on a platform like Steem where you cannot erase it. Maybe consider trying something else before you attract the wrong kind of attention. Some people love witch hunts, and they also happen to be the kind of people who will slit your throat for a sandwich. Consider your actions on Steemit carefully.
