How to delete all posts and threads from a spammer?

  • Woke up to thousands of new threads posted by a Chinese spammer and going through each one will take days. For the moment I've blocked him/her by IP but I'd like to know how to remove all content posted by that spammer.

    Is this possible?

    Many thanks.


    EDIT

    I found the answer: go to ACP/apps/bulk processing of threads.

    Delete this thread if necessary.
