Tor is not blocked in the US. It's a legal tool that anyone, including US citizens and residents, can use. However, organizations such as schools, libraries, and government agencies may block Tor on their networks for policy enforcement or security reasons. Using Tor does not exempt users from applicable laws or regulations, and some activities conducted through Tor may still be illegal. While Tor provides anonymity and privacy, it does not guarantee complete security or protection against all online threats. If accessing Tor is difficult, the issue may be due to technical problems or network disruptions. Trying a different device or network can help determine if the problem persists. For further assistance, the Tor support team can be contacted.
