I was trying to signup for a service provided by a website using Tor, the website prevented me and asked me to disable my proxy settings, he noticed me with the following:
Our checks indicate that you are connecting through a proxy at the moment. Please disable your proxy settings first and then try again. Thank you!
Then I tried a VPN connection with normal browser without any proxy settings, but the website still gives me the same notice.
My question is:
1- How can the website server detect my anonymity-based connection (Tor or VPN), what is the interpretation?
2- Is there a way to overcome this issue?
