+Anti AI Spam Policy
+-------------------
+
+OpenWISP welcomes meaningful contributions from people who take the time
+to understand the project, the problem they are trying to solve, and the
+impact of their changes.
+
+Contributions which shift the burden of understanding, implementation,
+testing, and review entirely onto maintainers are harmful to the project.
+This includes AI abuse: using AI coding agents, chatbots, or other
+automation to generate pull requests without adequate human understanding,
+verification, and testing.
+
+AI tools do not turn an inexperienced person into an experienced software
+developer. Contributors are responsible for understanding the project, the
+issue, and every change they submit. If a contributor cannot explain,
+maintain, and properly test the code they are proposing, they should not
+open a pull request.
+
+Maintainers reserve the right to close pull requests considered spammy or
+harmful to the project, including but not limited to:
+
+- unsolicited pull requests which do not have a related issue;
+- pull requests targeting issues which have not been opened, acknowledged,
+  validated, or accepted by maintainers;
+- pull requests with poor, incomplete, or untested implementations;
+- pull requests generated by AI tools or automation without enough human
+  understanding, review, and testing;
+- pull requests with repeated pushes over a short period of time, repeated
+  failed CI builds, or excessive automated review activity which wastes
+  maintainer time and consumes the limited CI and review tool credits
+  sponsored to the project. If these costs grow too much, sponsored
+  services may run out or stop being available to OpenWISP;
+- pull requests which show little or no evidence that the contributor
+  understands the project, the issue, or the proposed solution.
+
+Maintainers may temporarily limit contributions from contributors who
+violate this policy. Contributors who continue violating this policy after
+a temporary restriction may be banned permanently.
+
+When a pull request or contribution is closed under this policy,
+maintainers may provide only a link to this policy as the explanation.
