Let's say I live under an oppressive regime (don't we all?) How can I use social media anonymously, so I don't face reprisals from the government?

Mastodon, Lemmy, Reddit and other social media platforms restrict users who connect through TOR or a VPN.

Is there any way I can create an account on these services and use them anonymously?

Thanks in advance for any information and advice you can provide.

Let’s say I live in a police state. How can I publish a blog with complete anonymity? If I am found out, there is a high chance of imprisonment or death. What can I do so that the government cannot discover my identity?

I need a blog or website where I can publish articles, with a mailing list feature so I can send those articles out to subscribers.

What tools should I use? What steps should I take to protect myself?

I would greatly appreciate any information or resources that can help me with this.
