The idea was that one of your friends would be that human for let's say a week. You would pick the person based on your style (and matching biases?)...

E.g. Will's client would have button "let Derek handle this shit for a while" and Derek's client would have "accept dealing with Will's shitty spammers" (and it would be under well defined conditions).

Or in case of Roya I think multiple folks were interested in helping in some way.
