Hello, some time ago I accessed with the TOR browser a government page in my country Argentina and I got a notice from the page saying that it was going to be investigated by the administrator. Then I tried to enter the same page with a browser without proxy or vpn, that is to say with my IP from Argentina, and it prevented me from accessing it. Is it really safe TOR as they say? In my experience it is not. Well, I just wanted to share this experience. Best regards.
Tor is just a tool. It doesn't provide 100% anonimity, plus there are hundred more ways you can be identified, rather than your IP (like MAC address, screen width, installed software, DNS), everything can be used to reduce the ammount of people to just a few, and identify you pretty easily.
The fact that using Tor to access a government site (which are regularly targeted) is blocked is a common measure. If you personally were still blocked after closing Tor, my guess is your MAC address was blacklisted. There's no law against visiting the argentinian website with a VPN or Tor, as far as I know, so you can't be investigated (publicly) for that.
