You are not wrong. Personally I would DROP any bogons coming in on a WAN
interface. REJECT does not make sense in this case, if they are
unallocated or hijacked blocks the replies will not make it anyway. If
they are RFC1918 addresses that you are using internally, the replies
would be sent to your LAN which would not be desirable.
