+## Do Not Violate Copyright
+
+Only submit a PR with your own original code. Do NOT submit a PR containing code which you have largely copied from
+an externally projects, unless you wrote said the code yourself.
+Open source does not mean that copyright does not apply.
+Copyright infringements will not be tolerated and can lead to you being banned from the repository.
+
+## Do Not Submit AI Generated PRs
+
+The same goes for (largely) AI-generated PRs. These are not welcome as they will be based on copyrighted code from others
+without accreditation and without taking the license of the original code into account, let alone getting permission
+for the use of the code or for re-licensing.
+
+Aside from that, the experience is that AI-generated PRs will be incorrect 100% of the time and cost reviewers too much time.
+Submitting a (largely) AI-generated PR will lead to you being banned from the repository.
