Hi,

since I got a question about who is running OrNetRadar I figured I'd
answer this on list.

OrNetRadar [1] is a mailing list to publish and learn about
(automatically) detected events on the tor network (potential Sybil
attacks, undeclared families, anomalies, ...).
(There was no ML on lists.torproject.org with that topic.)

It uses Karsten's great onionoo data from

Directory authority operators are probably the perfect audience for such
a list since they are the only one with the power to react to events
(i.e. Sybil attacks), great to see some interest.

The list is meant to be filtered/sorted client side. I.e. if you do not
care about small relay groups or the daily bunch of Windows "default"
bots joining the network you can remove such incoming emails by creating
custom filters based on the subject (the groupsize is the last part of
the subject).

As time allows it I'd like to add more alert/detection types in future.

regards,
nusenu
