The goal of hash cash is to force someone to break the hash if they don't have the key. Since you can generate as many hashes of any length that you want, you would typically generate a very long hash for each trusted source, and then give that source the key. At that point, they can break the hash without any problems, but others would take years to break that particular hash. And if someone else DOES get hold of the key to a particular hash, all you have to do is invalidate it. The listserv will not be able to reach you with that hash, but by creating a new one and handing the key to the listserv, you've solved the problem. Note that this doesn't prevent the list from selling your address and key; it just means that your address is of extremely limited value to a spammer as you can change keys immediately.
