If the behavior is an egregious violation, the community member who +committed the violation may be banned immediately, without warning. +3. Otherwise, moderators will first respond to such behavior with a warning. +4. Moderators follow a soft "three strikes" policy - the community member may +be given another chance, if they are receptive to the warning and change their +behavior. +5. If the community member is unreceptive or unreasonable when warned by a +moderator, or the warning goes unheeded, they may be banned for a first or +second offense.

Open the index.html in your browser to +view them. It will also (due to -W) error out on any warning like Travis will.
