How do I delete all posts by a particular user?

[محروم.كوم]

A user has 700 posts and I would like to delete them all, or else delete all posts over 30 days.

From looking at the wording of the Prune option, it looks as if it will prune all the threads in which that user posts? Is that correct?

Prune by UsernameNote: This includes individual posts made by the specified user. User Name
