The trick is that both parties need to list each other as family for this to work. As per the man page..<br><br>"When two servers both declare that they are in the same 'family'..."<br><br>The attacker would need to be listed in every other relay's torrc for the attack you described to work. I'm pretty sure listing relays you don't control has no effect. -Damian<br>

</div> What is the limit on line length for such a MyFamily statement? What<br>
is the limit on descriptor length? Listing ~1500 nodes sounds like the<br>
sort of thing that wouldn't work very well.<br>
Also, my other question remains: what would stop me from listing nodes<br>
that I don't control in a MyFamily statement now?<br>
