@SmokeDetector Please see:
Are job offers spam?. What's discussed in that Meta post is more inclusive than just job offers for payment. The example given doesn't show an actual offer of money, just the solicitation of having someone work on the project. IMO, the differentiation is that the Q is primarily looking for a person to help off-site, rather than looking for an answer to an on-site question. IMO, the original version of this Q clearly qualifies.
