For contributions to journals and proceedings of conferences, we recently adopted the ACM rules
http://www.acm.org/about-acm/acm-code-of-ethics-and-professional-conduct
and also Spriger Verlag rules are recommended to follow
https://www.springer.com/gp/authors-editors/editors/publishing-ethics-for-journals/4176
We hope that those common rules are probably the best available and best formulated.
Generative AI and AI-assisted technologies should only be used in the writing process to improve the readability and language of the manuscript.
In the case of conference proceedings we also adopted "No show policy". It means, that papers not presented by an author or co-author will not be published in conference proceedings.
