Here is the information on voting at the sajha polls - One username can only vote once on one poll (no matter where they log in from). That is as far as the checks and balances go, in order to ensure at least some validity in the polls. People can always use different email addresses to register new usernames to vote again. Hence, votes in the internet can never be 100% accurate. Having said that, regarding the particular poll in question. The logs reveals the following. - Out of 241 votes, 206 IP addresses were unique - There were 17 extra votes supporting the Feb 1 move by IP address - There were 15 extra votes opposing the Feb 1 move by IP address Data as of 1:17 PM EST today. The above analysis could be invalid under two circumstances below: * If there are more than 1 users on the same network they would have the same IP address. If there are 10 users in a college they would all have the same IP address. Similarly, if there are 3 roommates (with broadband), they would all share the same IP address. * Users using dialup (or other services that allow different IP addresses) could get a new IP address each time they reconnect. Thus one person with more than one username could essentially vote more than once if they reconnected each time using different usernames.
