It's pretty clear that both parties have dropped the ball in a big way, in terms of sane BGP filtering practices.
It's amazing, isn't it? I have a customer of one my upstreams (Upstream A), at the moment, who are leaking my routes to another one of their upstreams (Upstream B). The problem is that Upstream B is re-announcing my leaked routes from their customer to the rest of the Internet. So both Upstream B's customer as well as Upstream B are at fault. That Upstream B is simply "accepting everything" their customer is sending to them without applying proper filters, or checking to confirm that what their customer needs to send them should come from them is absolutely and unacceptably shocking! A lot of people seem to have forgotten 2008. Mark.
