[tor-talk] >600 Tor relays without ContactInfo and similar properties

[nusenu]

Since the Tor directory authorities are no longer removing such undeclared relay groups
and I feel bad about sitting on this list without doing anything with it 
I'm posting it here for your information.

This is a set of over 600 Tor relays that got added since 2020-01-29  on a limited set of hosters.
They have some similarities in their sign-up pattern and properties.


Most of them are middle relays (non exit relays).

total guard probability: 3.6%
total middle probability: 10.1%
