The thing is, if it doesn't have the exit flag it cannot generate lots
of traffic from real good-intended clients, because it's quite hard
for clients to choose this Node as ËXIT in their path if it doesn't
have the exit flag. So the traffic comes from clients who specifically
added "ExitNode <fingerprint>" in their torrc and only use that Tor
instance for Bitcoin. So, someone build this custom Tor node for
themselves only, for plausible den. A pool could be the cause as it
was earlier discussed here...
The thing is I cannot find this node on atlas, globe or blutmagie can
you please provide fingerprint and IP address again? So I may ignore
it on my relays and talk to some people about it?
