Alex - Have any of your peers complained? I can't imagine anyone caring (strenuously) if a peer applies filters to bogus addresses. Every peer I have dealt with for a matter like that, while it may take time to get to the right people, have made no complaints about us doing the filtering or even adding the filtering (on a temporary basis) to their own border/core routers.
