What I was saying is that there are some of us who are tyring, within the boundaries set for us by RIPE, to announce as few announcements as possible for the space we have (ends up being /19s). There are other providers (including Sprint customers, and sorry to single out GSL but it was an easy target) who aren't. Your proposed filtering scheme gives providers like myself who are doing everything we can a problem, but doesn't actually incentivise some of the prime offenders (i.e. your customers) to do anything about the problem. Thus saying you are interested in working networks doesn't really cut any ice - there are many providers like us for whom no amount of renumbering within the current RIPE guidelines is going to give your routers less CPU load - all it will mean is the network will work *less* well (or rather your net will work less well in that it will give less connectivity). If you want to encourage people to use the optimum numbering schemes, make it hurt for those who can actually do something different first (i.e. anyone announcing loads of /22, /23 /24 routes etc.).
