Joomla! 1.5 
In version 1.5 mambots have become plugins, therefore you should look for the file /plugins/content/vote.php and change
$mainframe->registerEvent( 'onBeforeDisplayContent', 'plgContentVote' );
to
$mainframe->registerEvent( 'onAfterDisplayContent', 'plgContentVote' );
Joomla! 1.0 
You must hack a mambot, namely in file mambots/content/mosvote.php. Change
$_MAMBOTS->registerFunction( 'onBeforeDisplayContent', 'botVoting' );
to
$_MAMBOTS->registerFunction( 'onAfterDisplayContent', 'botVoting' );
