Error: 

array_merge($info['user_block_user_action']['hooks']['comment'], array('insert'));

Correction: 

array_unique(array_merge($info['user_block_user_action']['hooks']['comment'], array('insert')));

Description of the Error: 

array_merge() appends values instead of combining them when keys are numeric, as they are implicitly in the above array.
