------------------------------+--------------------------------
 I have an exit policy that looks like this on a relay running tor-0.2.9.9:
 {{{
 ExitPolicy reject *:*
 ExitPolicy reject (IPv4 Blocks):*
 ExitPolicy reject (IPv6 Blocks):*
 ExitPolicy accept *:(Ports)
 ExitPolicy reject *:*
 ExitRelay 1
 IPv6Exit 1
 }}}

 Even though the policy starts with 'reject *:*', atlas reports that the
 accepted ports are allowed over IPv6. All ports are rejected over IPv4.

 This was a big surprise to me.
