Why complete secrecy? The person whose vote you are purchasing doesn't even have to know which way their ballot is being used -- they can simply sign it and drop it off at the designated location, or, more feasibly, just scan the signed unfilled ballot and send it to the address they were given in exchange for some Bitcoins or something. The signature isn't a cryptographic one that contains a hash of the votes, it's just an image that can be copied. Both Tammany Hall and the Cook County Democratic Machine extensively used vote purchasing in addition to ballot stuffing and voter intimidation. Those are just the best documented cases; there have long been rumors of ballot purchasing and intimidation on the part of large unions. As for the relevant law, you sound more knowledgeable than I am in this field, so I'll grant that enforcing the laws is part of what made some forms of voter fraud less possible, but even a cursory glance at the text of the act shows that it is a mix of definitions of crimes and structural remedies, like keeping rolls of electors and permitting access to polling places.
