rather than simply recording a vote response I advise that you record more
the vote subject or id, vote response, timestamp, IP address, and cookie
value (if available), a validity flag (default: Y)

Store all these values in a database table.

validity flag can be an arbitrary value Y or N

create a maintenance script that can check your data and mark duplicates
flag as N when following cases are true.
case 1: consecutive rows where previous row has same values for vote subject
or id, response, IP and cookie value if set.
case 2: vote subject or id, response, IP and cookie value if set more than
once per day..hour..10 minutes

you could also dynamically generate an image with a code and force your
users to enter the code into the vote entry form.

This would also be added to your table codegen,coderesponse and your
maintenance script would make rows N where these values do not match.

These would certainly give you better vote results.
