How do they do it!!? PPC pharmaceuticals on Bing & Yahoo

Google, Bing and Yahoo have all banned prescription meds from advertising/ppc/sponsored links, however some are slipping under the radar somehow. I have seen it on the Scandinavian engine sites (.se, .dk, .no) but probably other countries as well.
Search for the following (im not allowed to post links):
Viagra on bing.se
Viagra on yahoo.se

Same goes for keywords like Levitra, Cialis, impotence etc!
Both dodgy generics sites and proper online pharmacies seem to appear in the sponsored links.
How the feck do they do this!!?
Any thoughts would be helpful!
Cheers!
