More appropriately, 

ip community-list exp PRIVATE-AS permit 65[0-9][0-9][0-9]:.*
ip community-list exp PRIVATE-AS permit 64[6-9][0-9][0-9]:.*
ip community-list exp PRIVATE-AS permit 645[2-9][0-9]:.*
ip community-list exp PRIVATE-AS permit 6451[2-9]:.*

route-map peer-in
   set comm-list PRIVATE-AS delete

As not to destroy all communities coming in, since preservation of data is
good. Ideally you'd want to strip any 'prepend' and selective advertise
communities from peers as well, since one would hope they're not depending
on you to do TE work for them....
