Violating these terms may lead to a permanent ban. 67 | 68 | ### 4. Permanent Ban 69 | 70 | **Community Impact**: Demonstrating a pattern of violation of community standards, including sustained inappropriate behavior, harassment of an individual, or aggression toward or disparagement of classes of individuals. 71 | 72 | **Consequence**: A permanent ban from any sort of public interaction within the community. 73 | 74 | ## Attribution 75 | 76 | This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 2.0, 77 | available at https://www.contributor-covenant.org/version/2/0/code_of_conduct.html. 78 | 79 | Community Impact Guidelines were inspired by [Mozilla's code of conduct enforcement ladder](https://github.com/mozilla/diversity). 80 | 81 | [homepage]: https://www.contributor-covenant.org 82 | 83 | For answers to common questions about this code of conduct, see the FAQ at 84 | https://www.contributor-covenant.org/faq.
