As Pansy is not likely to volunteer to be drained
No, but she may not have a choice in that matter if justice, or at least just punishment, is served. Such a punishment -might- just make Draco stop and think again (low order probability, but possible). Even if he doesn't, a lot of others likely will.
Oh, just a thought, but I expect that Pansy's lack of success is not going to embolden the others supporting "pureblood only rights".
