+# Modern Crypto Rules
+
+This page documents the rules for my Matrix room, `#moderncrypto:gnuradio.org`.
+
+Modern Crypto is part of the PSA community. See <https://anonymousplanet-ng.org/chatrooms-rules.html>
+
+---
+
+### Rules:
+
+- Keep it ~~legal~~ ethical
+  - Ethics take precedent over laws. For example, laws that ban encryption deserve to be broken.
+- English only
+- Be respectful to each other
+- Avoid FUD and/or disinformation
+- Avoid gatekeeping
+- No hate speech
+  - This includes racism, sexism, homophobia, transphobia, and other anti-LGBTQ+ behavior
+  - Hate speech will result in an insta-ban. *No exceptions.*
+- No spam
+- No trolling
+- No doxxing
+- No soliciting donations
+- No NSFW content (no Porn, no Gore, no Hentai…)
+- No pedophilia
+- Avoid drifting too much off-topic or move to an off-topic room like #bnonymity
+- *We are not lawyers. Behavior not covered by these rules may be handled at the discretion of any acting moderator(s).*
+  - *We enforce the spirit of the rules, not the letter.*
+  - *Citing technicalities or imprecisions in the definitions of rules won't save you.*
+
+**Violations of these rules may result in a PSA-wide ban.**
