if you want to stop shit like gass.. make the window popup to a https site that can only be gotten if you go to the main page.. so say you goto
http://www.domain.com/submit/ that will popup another window like
https://www.domain.com/submit/secure.php?some encryption that can only be gotten by hitting the
www.domain.com/submit/ page.. maybe just a string you update every 12 hours so that it has to be
https://www.domain.com/submit/secure...ecure=blahblah then update blahblah on
www.domain.com/submit/ every 12 hours to be something different and
https://www.domain.com/submit/secure.php?secure=??? will only work if it has the variable that is on
http://www.domain.com/submit/
duno if that makes sence.. but that would stop 99.99% of auto submissions
