It's pretty clear that both parties have dropped the ball

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.
