Any member of the community may report any situation that violates the +Adafruit Community Code of Conduct. All reports will be reviewed and +investigated. +2. 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. Repeated offenses will result in the community member being +banned. + +## Scope + +This Code of Conduct and the enforcement policies listed above apply to all +Adafruit Community venues.
