well.. the problem of course is that you pull in the traffic from the
aggregate transit prefix which costs you $$$ but then you offload it
to the customer via a peering link for which you are not being paid
its a pain but you cant stop the customer from doing it.. you can
however filter your customers prefix at the IX (an ASN filter would
be easiest)
if you think it is malicious, you may want to hit them with something
official (IANAL)
