> has any idea of what Twitter is detecting as spam and what not, and thus can't actually judge how good a job is being done. That's wrong. Results can be seen even if the process is not transparent. If every bridge the engineer builds collapses, I can judge him without looking into all the drawings. If every business the entrepreneur runs collapses I can make conclusions from that, even without seeing the books. If there's a lot of garbage on Twitter, I can judge it's doing a bad job even if I don't get to see its algorithms.
