Plugin is not coded up to WordPress standards and has not been internationalised. Therefore it's fully incompatible with a plugin such as WPML.
It generates a category that cannot be deleted. You can add other categories, but those also cannot be deleted.
Worst of all, after deactivation and deletion of the plugin you're stuck with a new table in your database called [wp_prefix]_randomtext.
If I would have been able to give 0 stars I would have.
