I don't think we need to decide which is the lesser, we should just deal with them as we can. Self voting can be entirely removed by disabling it on a blockchain level.
In the meantime as we campaign for this, we are making a bot to "tap people on the shoulder" about this issue with small flag for self votes on comments only (announcement here and here). For normal posts, we decided it wouldn't be fair to do that since it's the default steemit.com interface behavior, so I opened a change ticket for that, hopefully it's accepted.
As for multiple accounts, they can be useful, for bots or organizations, etc. I do not agree with 1 person 1 account. But for self voting, I don't know it's probably a serious issue. I think that because you have to split your stake between multiple accounts to do that it will never be as effective as using just one account, so not as bad as self voting. But to really solve it I don't know.
I do think that just because it is now known the first one should still be solved, we needn't choose between them.
Very good points and honestly I think I agree after reading your reply. I also just realized how awesome bots can be as you could literally as a community member make a bot that did that, right? Replied to self voters on comments? I wonder what the back lash would be lol. For instance, some people upvote themselves on comments just enough to be at the top of the list. Not 100%. Maybe just $0.10 worth.
For sure. We are not going to have the bot comment because you do you open the bot up to flagging itself. Just a little pinch of a flag instead to get the point across.
The point is that if vests are split between accounts they are necessarily small by virtue of being split.
