Next time you upgrade WordPress, remember that the devs who write it hate you and will progressively make it harder and harder to turn off their goddamned wpuatop function that fucks up your entries.
Currently this is what you need to do to kill it since nothing else works.
remove:
$content = apply_filters('the_content', $content);
$content = str_replace(']]>', ']]>', $content);
from /wp-includes/post-template.php
