If the new service is centered around HackerNews members you can keep the service spam free(or at least close to it) by checking projects for sale against members profiles here on HackerNews. A few active moderators in the beginning can set the tone for the whole service. After all how many projects would be up for sale at any given time? It would be great if someone can set up a poll here to ask developers if they are interested in getting some pay for small/weekend projects they have.
