My point was your module was equivalent to

package scrubber1;
require Exporter;
use config1;
use 5.010;
use Net::FTP;

our @ISA    = qw(Exporter);
our @EXPORT = qw(
  get_ftp_object
  get_html_filenames
  kill_files
);

sub get_ftp_object {
  use strict;
  my $sub_hash = "my_ftp";
  my $domain   = $config{$sub_hash}->{'domain'};
  my $username = $config{$sub_hash}->{'username'};
  my $password = $config{$sub_hash}->{'password'};

  #dial up the server
  my $ftp = Net::FTP->new( $domain, Debug => 1, Passive => 1 )
    or die "Can't connect: $!\n";
  $ftp->login( $username, $password )
    or die "Couldn't login\n";
  return $ftp;
}

strict is a pragmatic module, so its position might change things, but you can safely move it to the beginning, too, as both @ISA and @EXPORTER are correctly declared with our.
