Below is a summary of rules you need to follow if you want to have an account on this server of Mastodon:
No illegal content.
When people say stop, stop. If someone says you're being hurtful, apologize and stop (even if you don't agree).
Social.Rights.Ninja is a private instance, I talk mostly about computers, software, maths and chiptune music.
Don't be an asshole, don't hurt people; you will be banned.
