Comment (by dgoulet):

 Based on the latest three months of blocking malicious HSDirs, I can count
 _6_ dir auths that respond to the reject rules in < 3 days. I think out of
 those, 3 or 4 apply the rules in few hours after push to dirauth-conf git.

 Having 5 dir auths with the `Valid` flag in known-flags, it means majority
 is 3/5 which is one more than the original proposal here but we have at
 least 4 dir auths that are fast responding so I propose we set that to 6
 dir auths with `Valid` in known-flags which moves the required majority to
 4/7 (which is good because we have 4 auths that are fast).

 I have no idea why this is still weirding me out that is 4 dir auths can
 choose who is out where right now we need majority of 5/9... Plus side is
 that 4 dir auths colluding is (maybe) unlikely.
