I am a Japanese university students.I studied the Tor. I want to block tor users to access the web server.Is there a way to block access other than to block the exit node of the tor.
Tor is just a network instrument, there are many of them... The crime exists inside malicious user's mind, and it has no relation to any tool he uses. So - blocking Tor won't help you a bit, if your task is to protect the website from malicious activities. My good advice to you - forget about 1990-years AtGuard tactiks with a blocklists in txt files: it does not work at all nowdays. Focus on hardening and guarding your website itself, and it will work fine regardless of the connection methods used by user.
