Two questions:
1) How would the feedback loop work from users who do not receive a response?
2) Are you concerned about a possible "chilling effect" for startups that don't want to post for fear of being spammed?

Presumably you guys don’t want to create a report button for just this situation. I never know what to think when I see downvotes in the Who’s Hiring thread. There’s no way for me to tell if someone hates the CEO (eg, if Twitter posted job openings), or they’ve noticed the same position filed three months in a row. I’ve seen a few of those before you got around to detaching them.
