The non-customer longer routes may be beneficial, so you may want to 
write a filter to drop the longer routes originating from their AS but 
permitting the longer routes (maybe only /25 and /26?) that are 
transiting their AS.  You may be able to distinguish customer routes by 
matching on communities assigned by the provider, YMMV.
