A more traditional voting system would have the same problem. He'd instead just put himself at a polling location and do the same trick there. The fact that he had to pay people to collect individual absentee ballots means this sorta fraud is very hard to scale, easy to beat with some basic education and easily identifiable. Of course a lot of this goes out the window if you're doing it to help a party and that party has zero integrity but at least if one voting individual brings up an issue it can cause a ripple effect. Part of the problem is also that we don't seem to take absentee ballots as serious as we do when we have full vote by mail.
