You could use SQL to find all the posts made by the reporting account whose title matches the reporting message (wildcarded) and then change the IP address of those posts.

PHP Code:

SELECT * FROM `post` WHERE `userid` = 1 AND (`title` LIKE 'Multiple Registrant%' OR `title` LIKE 'Multiple Login%'); 


I suggest that IP address for reporting should be 0.0.0.0 to avoid confusion.

The following SQL query should reset the IP Address to 0.0.0.0 and assumes that the userid that you are using to make the reports is 1

PHP Code:

UPDATE `post` SET `ipaddress`='0.0.0.0' WHERE `userid` = 1 AND (`title` LIKE 'Multiple Registrant%' OR `title` LIKE 'Multiple Login%'); 


You could refine this further by selecting posts that were made in a particular forum.
