Comment:

 Clarified bug title.

 By the way, nick3 is wrong: the attack is to steer traffic towards
 particular nodes by listing a very large family. And it doesn't work on
 recent versions of Tor, because it checks for mutual family relationships.

 OnionOO has effective_family and alleged_family, I suggest they are
 coloured differently in the Atlas family list, like we currently colour
 missing relays differently.
