Funky... yeah the self vote can be used as a way to elbow your comment to to the top of a comments section. Sad to see that go, but I'd give that up to have whales up biting themselves to lambo land.

Or maybe have it so self votes are always just 1% of voting power or something.

Yeah, it's impossible to enforce and should not even be considered:

Sock puppets, multiple accounts, delegation, trading votes, etc.
