[rust-dev] New moderation policy

Hey! This is a new section for our development policy covering moderation guidelines. It tells both community members and moderators the mechanics of when and how a conversation should be moderated. This involves no changes to the Rust Code of Conduct; it is making explicit the informal process that is already in place for dealing with violations. It is posted on the wiki: https://github.com/mozilla/rust/wiki/Note-development-policy#moderation ## Moderation These are the policies for upholding our community's standards of conduct in our communication channels, most notably in Rust-related IRC channels. 1. Remarks that violate the Rust standards of conduct, including hateful, hurtful, oppressive, or exclusionary remarks, are not allowed. (Cursing is allowed, but never targeting another user, and never in a hateful manner.) 2. Remarks that moderators find inappropriate, whether listed in the code of conduct or not, are also not allowed. 3. Moderators will first respond to such remarks with a warning. 4. If the warning is unheeded, the user will be "kicked," i.e., kicked out of the communication channel to cool off. 5. If the user comes back and continues to make trouble, they will be banned, i.e., indefinitely excluded. 6. Moderators may choose at their discretion to un-ban the user if it was a first offense and they offer the offended party a genuine apology. 7. If a moderator bans someone and you think it was unjustified, please take it up with that moderator, or with a different moderator, **in private**. Complaints about bans in-channel are not allowed. 8. Moderators are held to a higher standard than other community members. If a moderator creates an inappropriate situation, they should expect less leeway than others. In the Rust community we strive to go the extra step to look out for each other. Don't just aim to be technically unimpeachable, try to be your best self. In particular, avoid flirting with offensive or sensitive issues, particularly if they're off-topic; this all too often leads to unnecessary fights, hurt feelings, and damaged trust; worse, it can drive people away from the community entirely. And if someone takes issue you with something you said or did, resist the urge to be defensive. Just stop doing what it was they complained about and apologize. Even if you feel you were misinterpreted or unfairly accused, chances are good there was something you could've communicated better — remember that it's your responsibility to make your fellow Rustians comfortable. Everyone wants to get along and we are all here first and foremost because we want to talk about cool technology. You will find that people will be eager to assume good intent and forgive as long as you earn their trust. *Adapted from the [Node.js Policy on Trolling](http://blog.izs.me/post/30036893703/policy-on-trolling)*
