Here is the full text of the email I received, which contains no evidence for the alleged terms of service violation:
> Access to the raxod502/AdguardFilters repository has been disabled by GitHub staff due to a terms of service violation.
> When making content moderation decisions, we consider information from a variety of sources, including: account profile data, information contained in submitted reports/notices or discovered through our own voluntarily initiated investigations, and context around the contents of the repository.
> If you wish to regain access to the disabled content or would like to dispute that a violation occurred and can provide additional information to show that a different decision should have been reached, please review our Appeal and Reinstatement Policy and submit a request via our form.
> You may review our terms of service here: GitHub's Terms of Service
> Please feel free to Contact GitHub Support if you have any questions.
