We are trying hard to make F available from our anycast nodes on its 
IPv6 address. Finding exchange points which (a) will give you v6 
addresses and (b) have peers which will peer with you over IPv6 is not 
trivial, however.

If that doesn't make it through your filters, then your filters are 
broken. 2001:500:1::/48 is an ARIN micro-allocation, and it is 
perfectly legitimate to advertise it with no covering /32 supernet.

Incidentally, F is also announced as a /48, and is also an ARIN micro 
allocation (the first one they made, in fact). 2001:500::/48 seems to 
get through your filters ok.
