Re: Unique User Hashes

'Twas brillig, and Ian at 18/02/09 07:09 did gyre and gimble:

We dont have registration - its a once off vote anonymously using the hash in the original email. We dont want registration otherwise it would be much easier - but this was the best way I could think of without user registration :/

Do you have to invite people to vote or can anyone come along and cast? If the former you could email a UUID token to them or similar as part of the link. Once that UUID was "spent" it wouldn't allow voting again. I say UUID as a regular auto-incrementing id would be fairly easy to guess ;) Of course this may not be appropriate in this circumstance.
