There was an interesting technique for bribery in an exhibition at the British Library on the history of elections which was that the voter has a wager with the candidate that the candidate will win so if the candidate wins they have to pay a sum of money to the voter.
A reason why votes are invalid if signed by the voter is to avoid bribery. If the vote can be identified it is invalid.
