I'm not sure of how the thread API works (if there is any) to cause messages to be removed, so I don't know how that'd work. Though you are admin on that wiki and you do have the delete permission which is all that is needed to delete thread comments (or any page). I might add an optional config in the future to not delete forum threads, so for now you could try using the "Delete Selected" option on WHAM if this becomes a common issue.
