Hi Georg, First of all, thanks to all of you for the effort writing up the proposal! I saw that email obfuscation was discussed but no solution was proposed. I want to throw in some ideas about obfuscating the email centrally: - Let's not publish cleartext email in any public descriptor, and

Hey John, Perhaps one thing you can try in debugging is to run tcpdump on the server in question, to check if it is indeed sending out a lot of port-scanning packets. You can use the following command to filter for port 22 only. Make sure to test with tor turned off as well. "*sudo* *tcpdump -vv
