Actually, this is a fairly common routing policy.  I think you will find
other networks do the same thing.  It is an entirely sane thing to do, and
it helps force people to aggregate their routing announcements properly. 
Also, it protects you against fat-fingers that people sometimes do (one time
UUnet announced 50k extra /24s in classful B space).
