Ah, missunderstood who was leaking.

The other service provider your customer was peering with obviously didn't
filter the customers announcements.
Your customer would add an additional prefix hop, thus increasing the length
so that hopefully the effects are too bad.

Even with setting no export etc, should your customer want to break things
he can.

I would speak with his service provider, and ask him why he accepted your
addresses.

Aren't the routing policies included in the whois AS data anymore?
