I really like the concept of a 'spam worker'. That would make interview panels into 'spam worker filters'. :)

Since this article has done well, I will probably write down my thoughts on mitigation for a future article, but if you can't wait, the last section in the linked WebSci paper has most of the written text on mitigation I have. Unfortunately I don't have any advice for dealing with it as a content author, only from a system-wide perspective. Given the feedback here and new material I have explored since, there will probably be significant differences between that and the article here, but the core will probably remain in some form.

The methods I have in mind (namely, discarding singletons such as Google and working on distributing the logic and focusing on local rather than global judgments) can probably be applied to real-world institutions and governments, but I haven't spent nearly as much time thinking about this as I have the online counterparts, so there is still work to be done there.
