Think about what that means for the most important cases we are trying to solve for - the 0 minute self voters in front of bid bots
The fact that this is the most important case you're trying to solve for - and not the new user who just wants to use their vote as a vote and not have a chunk of it taken away for bizarre reasons - is incredibly terrible system design. You need to support that new user first and then figure out what you're doing about the other.
My proposal solves the problem of extra curation going to authors and bots. It actually does a better job of it than HF20 does. You just don't like that it still allows voters, including the author, to give 100% of the value of their own vote to the author. Even though authors will still be able to do this trivially anyway and you're just taking that option away from everyone else.
