Tor

You might recall that Tor has been restricting the possible amount of Tor relays per IP address to 2, mainly for Sybil prevention reasons.[1] We bumped that limit to 4 earlier this year[2] to make better use of available resources and considered back then bumping that limit further to 8 relays per IP address.

I've good news for everyone looking forward to raising that limit further: after an investigation into the effects of allowing 4 relays per IP address[3] we think it is overall beneficial for the network and our users to raise it further to 8.
