All security is through obscurity. Obscurity of a bitting pattern, of a private key, of a password, of an algorithmic optimization strategy.
That phrase, and the sneer encoded in it, does have some wisdom, but it's more complex than "If you're relying on obscurity you're doing it wrong", being a criticism of a much more specific fault than relying on obscurity, which is, after all, the only thing that has ever worked. That criticism is this: Suppressing knowledge of security faults provides only a false sense of security in a system whose faults...
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?
