Are you sure that level3 filters external routes against all IRR, or
(likely) is it just routes they are willing to hear their own from
customers?

If they filter global routes in the way you describe then I believe
their customer base will be disappointed once the radb purges unpaid
objects on April 2 (http://www.radb.net/)
