Do you not prefix-list customers? That'd have solved this, eh?
The problem is: the route is coming from our upstreams / peers.
that means they also did not filter it out.......

oh bummer ;( that's not us sending that is it? 
Honestly, prefix
filtering should apply in both directions. You'd want to be sure that your
upstream didn't send you 1918 prefixes, or bogons or even your internal
infrastructure, eh?
hopefully a simple prefix filter as in the one mentioned a few times from
cymru would fix it for you
