Code of Conduct

Prior art


The short version

  • Don't harass anyone
  • If someone is harassing you, report it to a moderator
  • Have fun
  • Be excellent to each other

Handling harassment

If you are being harassed, please report the user using the "…" button and then "Report." For urgent concerns, please DM a moderator.

If you engage in harassing behavior, the moderator may take any action they deem appropriate, such as a warning or an expulsion.

The above rules may change at any time, and you may be banned at any time based on the moderators' judgment.

Privacy policy

What will we do with your data? Nothing. How will you be influenced by advertisers? You won't; brands and non-humans (other than fun/useful bots) are banned. How will we aggregate your data in order to improve your service… none of that.

We will never share your data with anyone else, except in the case of valid legal requests if it comes to that. (Hopefully it won't come to that!)

Understand though that this instance is run by me and my friends, and (as is the case with all Mastodon servers) we potentially have access to your data, including DMs. The back-end is also not encrypted. If this is not okay with you, this might not be the instance for you.

Also, for truly private data sent between two people, Mastodon offers no E2E encryption. So use Signal or WhatsApp for the things you really want to be private.

More privacy measures on Free Radical:

  • Our robots.txt file asks crawlers not to explore the site.
  • HTTPS is used everywhere thanks to Let's Encrypt.
  • No ads or trackers.
  • Links are direct URLs rather than tracking redirects.

Moderation notes

These are longer explanations of comments in the Unavailable content section below.

  1. This is purely a practical matter. These instances have been decent neighbors.
  2. I took a poll of local users, and the overwhelming response was that Free Radical residents wanted to preemptively defederate from Gab and its friends.

Compliance

We are not subject to either the CCPA or GDPR. While we support privacy laws and strive to meet or exceed the requirements of the major ones we know about, they do not apply to us. As such, we will not reply to requests regarding them.
Instance rules
  1. No commercial accounts, advertising, or excessive promotion.
  2. No bots, unless they're cute, funny, or useful. Bots should avoid posting to the public timeline.
  3. No gore or graphic violence.
  4. Content that is borderline NSFW or could be construed as NSFW at a glance should be put behind a CW (Content Warning).
  5. No racism.
  6. No sexism.
  7. No discrimination based on gender, sexual minority, sexual orientation, disability, physical appearance, body size, race, ethnicity, religion (or lack thereof), or national origin.
  8. No xenophobia or violent nationalism.
  9. No sexual depictions of children.
  10. No holocaust denialism, Nazi symbolism, or promotion of National Socialism.
  11. No stalking or harassment.
  12. No fake accounts unless they are clearly labeled as such.
  13. No solicitation of prostitution.
  14. No Republican politicians, especially from Florida or Texas. The First Amendment overrules dumb state laws.
  15. No COVID-19 misinformation. See https://blog.freeradical.zone/new-junk-medical-advice-policy/ for more information.
