Title: Disable negative voting on workers
Authors: Daniel Larimer <dan@cryptonomex.com>
Status: Draft
Type: Protocol
Created: 2015-03-09

# Abstract
This proposal fixes a potential attack vector that might be exploited by rich shareholders that hold more collective voting power than the last approved worker (usually a refund/burn worker).
# Motivation
A whale of a group of whales can take funds from the reserve pool by creating a worker and instantly approve it with his stake. Shareholders and proxies can disapprove the new worker but only have a small time-window before the attacker makes a profit.
# Rational
Pro-active downvoting is a losing proposition. An attacker can create 1000 workers and the network will not allow you to down-vote so many workers. The only real solution is to *upvote* refund workers or removing DOWNVOTING is the actual solution to this attack.
Since upvoting of refund workers results in a higher barrier of entry for new legit workers, the solution proposed here is to remove down voting entirely.
Furthermore, a negative vote is equivalent with upvoting all alternatives and results in slightly narrower gaps between votes. It compares pretty will with comparing -1 with +1 (currently) and 0 with +1 as in this proposal.
# Specifications
This proposal could be implemented by removing the ability to cast negative votes or by not taking negative votes into consideration during vote counting in the maintenance interval.
