If my customer notices that transit traffic has been going around him, he may be grumpy. I prefer happy customers.Okay but:1. Your customer/customer's customer is the one doing the broken routing here not you.. if he wants to be grumpy you should point him in the direction of the guy who is announcing the bad routes in the first place!
s/broken// and s/bad// 'broken' and 'bad' are all a matter of perspective here.
2. If I'm following this, your peer pays your customer? So you are peering with your customer's customer? If that was me I would either depeer them or tell them that you have an issue and need it resolving urgently or you my depeer them.
It's an MLPA policy based exchange (and probably just using a central route-server) not bi-lateral peering. De-peering isn't possible here.
It's not an excuse for lack of filters, but as the OP pointed out, the filters weren't expecting the routes from their customer's customer.
