Most of the forums I've seen have a "report spam" feature that could be made more prominent, but human moderators are also valuable.

Along the same lines, I know there are independent product developers (iOS apps, Android apps, web apps, etc.) who are tired of doing email support themselves, but find it hard to find competent contractors to do thoughtful first-level support for them. This usually doesn't require advanced technical skills, mostly just being able to interpret vague descriptions, escalate important reports, and respond with polite standard English. I imagine building up a good reputation on a public Q&A site (the Apple discussion forums or something) could be a helpful first step for this, and then using connections to get an initial client or two who can vouch for you.
