The only issue with this regex (and the poster's original idea as well) is it will not properly capture the username if it contains ' on '

Noted. So we capture up until the last ' on '. 

use strict;
use warnings;
my $source = 'Posted by getting on my nerves on September 04, 2003';

if ( $source =~ /^Posted by (.*?) on (?!.* on )/i ) {
  print qq("$1") . "\n";
}
