I found this too while searching for a solution, but i don't want to have to do it for manually every thread of a user i delete/that gets deleted in a cleanup process.

(Also i am pretty sure that the query would still return empty since the username doesn't exist anymore, but can be accessed via {vb:raw post.username})

So changing the template query seems the better solution to me. (And i don't have to install another mod that may or may not interfer with other mods/custom modifications)
