Ransomware links are usually opened from emails and Tor is not running on company computers. Users cannot install anything either. How are they supposed to reach the hidden services? Users can bypass this blocklist with bridges from their private devices. There are private things that are none of the sysadmins' business and for this some users use Tor or VPN. > Secondly, running multiple services from your Tor relay is generally > considered bad advice if I understand correctly.

On the other hand, we want more relays at universities. Many users cannot reach the mirror Halifax = ftp2.de.debian.org We should perhaps consider at the relay meeting on Saturday whether several relay operators or the Tor Project could write to dan.me.uk. He shouldn't make it so easy to activate the non-exit list. For example, UniFi devices are often installed by inexperienced admins. They simply click on all the block lists without knowing what they are. -- ╰_╯ Ciao Marco! Debian GNU/Linux It's free software and it gives you freedom!
