https://atlas.torproject.org/#details/3CA834833A7D8C7A3473BA21A4588EBCE1281AFC lists "reject 1-65535" under the ipv4 exit policy summary (fine), but then

accept 213.0.0.0/8:8333
accept 213.0.0.0/8:443
accept 213.0.0.0/8:6667
reject *:*

under the ipv6 exit policy summary.

Oh wait, that's under the "exit policy", and there's a stray line "ipv6 exit policy summary" with nothing under it?

Maybe it shouldn't list an ipv6 exit policy summary if it isn't planning to list an ipv6 exit policy summary? :)
