"Consider consultant Clay Herbert, who is an expert in running crowd-funding campaigns for technology start-ups: a specialty that attracts a lot of correspondents hoping to glean some helpful advice. As a Forbes.com article on sender filters reports, "At some point, the number of people reaching out exceeded [Herbert's] capacity, so he created filters that put the onus on the person asking for help." Though he started from a similar motivation as me, Herbert's filters ended up taking a different form. To contact him, you must first consult an FAQ to make sure your question has not already been answered (which was the case for a lot of the messages Herbert was processing before his filters were in place). If you make it through this FAQ sieve, he then asks you to fill out a survey that allows him to further screen for connections that seem particularly relevant to his expertise. For those who make it past this step, Herbert enforces a small fee you must pay before communicating with him. This fee is not about making extra money, but is instead about selecting for individuals who are serious about receiving and acting on advice. Herbert's filters still enable him to help people and encounter interesting opportunities. But at the same time, they have reduced his incoming communication to a level he can easily handle."
