I would just make a substack or a self hosted ghost website unless you’re really invested in the development process.
I would just look at sites like https://apnews.com/ or https://www.bbc.com/ and see what they do, but I don’t think you technically need anything, plenty of people have wordpress blogs and substacks without a legal section. What’s the difference between your website vs a twitter account vs a substack where you live, probably not very much.
I’m sympathetic to people who were talking directly to a federal agent, except in the case of pedophilia. God forbid they just arrest the person for running an illegal business and not try to entrap them. By doing that they probably contributed to him getting the pardon in the first place.
