Limit 1 vote per IP Address?

Question

What I really want is to limit 1 vote per person but the next best thing i can think of is limit 1 vote per IP address to prevent malicious users/hackers from severely tempe

Answer 1

Generally, yes, what you would do is have a database table for the votes, and simply store choice+ip address - then when inserting, do a DB query to see if an entry already exists with the given IP.

The ideal solution would be to tie votes to user accounts which are in turn linked to more concrete presence (such as a credit card, cell phone, or other less-easily-multiplied identity source).
