The truth of a view is more important than whether or not it's abhorrent.
Amen. But the LW Terms of Use state:
You are explicitly prohibited from: [...] Posting or transmitting content through the Website that is harassing, threatens or encourages bodily harm, constitutes hate speech, or advocates for the destruction of property;
This case went beyond LW's usual attitude toward debate; this was explicit advocacy of violence, which should always be treated as Serious Business.
Did you mean for the "advocacy of violence" link to go to https://wiki.lesswrong.com/wiki/Deletion_policy#Hypothetical_violence_against_identifiable_targets instead?
I've gotten sufficient evidence from support that voiceofra has been doing retributive downvoting. I've banned them without prior notice because I'm not giving them more chances to downvote.
I'm thinking of something like not letting anyone give more than 5 downvotes/week for content which is more than a month old. The numbers and the time period are tentative-- this isn't my ideal rule. This is probably technically possible. However, my impression is that highly specific rules like that are an invitation to gaming the rules.
I would rather just make spiteful down-voting impossible (or maybe make it expensive) rather than trying to find out who's doing it. Admittedly, putting up barriers to downvoting for past comments doesn't solve the problem of people who down-vote everything, but at least people who downvote current material are easier to notice.
Any thoughts about technical solutions to excessive down-voting of past material?
