Blogging on the clearnet exposes authors to surveillance, harassment, legal pressure, and censorship. An author's IP address is logged by their hosting provider, their domain registration is public record, and their readers' visits are tracked by analytics scripts, ad networks, and ISPs. A .onion blog eliminates these exposure points entirely.
For journalists reporting on government corruption, whistleblowers documenting corporate malfeasance, activists organizing in authoritarian countries, or anyone whose writing could put them at risk, a Tor-hosted blog provides meaningful protection. Readers access the blog through Tor Browser, and neither the reader nor the author reveals their location or identity.
Even if your writing is not controversial, hosting a blog on Tor is a statement about the importance of free expression and privacy. It normalizes the use of Tor for everyday content and helps combat the stigma that surrounds the network. The more legitimate content exists on Tor, the stronger the network's privacy properties become for everyone.
