Fugitif, try to use TOR (www.torproject.org) implemented in Vidalia bundle - that will enable you to select unique nods so that you'll get more votes. Using TOR via script is possible but i have no idea how to write a script that uses only unique nods (usually it uses the same nods as 3-5 minutes before). Check it here (sorry in Russian) http://raz0r.name/mysli/ispolzuem-tor-kak-istochnik-besplatnyx-proksi-serverov/
I'm already using it (tor+torbuton plugin for firefox) but works very slowly and I need 150 more votes lol. coz the contest ends within 5 days . anyway thanks for the replies guys
