I've made this change already, as it's not really a "change" to the rules, but more clarifying a bit of wording that hasn't been interpreted clearly.
Previously, the text of the "Voting" rule stated:
Voting: You may vote for any reason you like, so long as your reasons are based on the content of the article. Do not downvote/upvote based on your opinion of the author, an effort to manipulate averages, or trying to win contests through attrition. This is considered malicious voting.
The text now reads:
Voting: You may vote for any reason you like, so long as your reasons are based solely on the content of the article. Do not downvote/upvote based on your opinion of the author, an effort to manipulate averages, or trying to win contests through attrition, as this is considered malicious voting. Advocating for voting on an article for reasons other than content is strictly against the rules.
It was always intended for "an effort to manipulate averages" to include "vote brigading", but it hasn't been interpreted as so, and several staff members — including Kaktus, Kalinin, Silber, Light, Crayne, and even Burns — have made convincing arguments that clarification was needed. I have updated the rule already to keep there from being issues, but everyone is more than welcome to weigh in if they feel that there's an issue with the current wording.
