You can't filter out ASNs; you can only filter out the prefixes which
carry those ASNs as attributes.
So what you are actually saying is: "these prefixes must be invalid if
they have XYZ attribute". It's a bit like deciding that an E-mail is
spam based on whether the sender has reverse DNS, or provides a valid
EHLO name.
If you drop the route, then you may be hurting the remote network a
little bit (by not being able to reach you), but you may also be hurting
your own customers (by not being able to reach the remote network)
If your customer says they can reach the remote network through every
other ISP they have tried but not yours, they are going to blame you.
