The Tor network has more than 6 000 relays. Organizations running Tor relays include universities like the MIT, activist groups like Riseup, nonprofits like Derechos Digitales, Internet hosting companies like Private Internet Access, and so on. The huge diversity of people and organizations running Tor relays makes it more secure and more sustainable.
If connecting to Tor is blocked or dangerous to use from where you are, for example in some countries with heavy censorship, you can use <i>bridges</i> to hide that you are connected to the Tor network.
You can publish a blog or manage an email account entirely from Tails. If you only access it from Tails, it cannot be related to you. You can store documents and images related to this different identity in your Persistent Storage, keep your passwords in <i>KeePassXC</i>, have a dedicated email account in <i>Thunderbird</i>, etc.
