Question Delete all entries from a specific user in a single "batch" operation?

We have a user at our forums who has decided to abuse the like/dislike system. He's gone on a disliking spree hitting over 600 posts in a short span of time. I have since banned the user, but now I'm still left with all these useless dislike entries. I see that I can go in and delete the entries one by one, but I do not see a method for deleting all of the entries at once via a "batch" type operation.

Is this possible?

DELETE FROM dbtech_thanks_entry WHERE userid = x

Remember to add the table prefix, and replace x with the userid of the banned member.
