Main post on Meta SE with some history, details, explanations, and calls to action.
Here, in short:
As of June 5, 2023, I am on the general moderation and curation strike. As a moderator of Computational Science SE, I protest the breakdown of communication and trust between the corporate (Stack Overflow Inc.) and its communities. Particularly, the last straw was the sudden introduction of the new AI-generated content moderation policy, which (together with not yet publicly announced guidance given to moderators), effectively makes reasonable moderation of such content impossible.
This is against the wishes of many SE communities, as well as my understanding of the quality content curation that makes Stack Exchange a valuable resource. See also Stack Exchange is failing its community and What has happened to lead moderators to consider striking? for more details.
Has AI-generated content problem already been a major issue for Computational Science SE? Not yet, as far as I know. However, many other sites have been, and its non-automated curation was essential. So, for Computational Science SE it is just a matter of time.
A general moderation strike is being held until the concerns laid out in the open letter are addressed. Moderators, curators, contributors, and users, you are welcome to join in by signing your name in the strike letter.
