It seems thata hosts sending large amounts of NTP traffic over the public Internet can be safely filtered if you don't already know that it's one of the handful that's in the ntp.org pools or another well known NTP master.
You have that backwards - you can (possibly) safely filter it if you can establish *for certain* that it *isn't* in the ntp.org pools.
