This appears to be all you need to polljack a Daily Mail poll.

vote.pl

#!/usr/bin/env perl

use strict;
use warnings;

use Data::Dumper;
use LWP::UserAgent;

my $url = 'http://www.dailymail.co.uk/dwr/call/plaincall/AjaxPoll.vote.dwr';

my %form = (
  callCount => 1,

my $resp;
my $ua = LWP::UserAgent->new;

foreach (1 .. 500) {

  $resp = $ua->post($url, \%form);
  sleep rand 5;
}

print Dumper $resp;

Not that I'd encourage anyone to do anything as dishonest as faking votes on an online poll.

You could probably just hardcode it to vote "No" and run it via cron.

That would, of course, be undemocratic :-/

But I notice that the percentages on the "Should we use BCE/CE instead of BC/AD?" poll have gone from 9%/91% to 24%/76% in the last hour or so. I wonder what they'll say in the morning whistles innocently

I was thinking of it more as "choosing sensible defaults". :-)

Oh, right. Yes. Except that in this case the right answer is "yes".
