Update August 2nd, 2023:
After intense negotiations with representatives elected by the striking moderators, Stack Overflow, the operator of the Stack Exchange network, has agreed to a number of changes.
You can find details about the negotiations and changes here:
Moderation strike: Results of negotiations
For those not aware, moderators and curators from across the StackExchange network are ceasing their moderation activities in protest of recent policy changes by StackExchange. In particular, there is a new policy, part in public and frustratingly somewhat different and more restrictive in private, against removing content generated automatically by AI programs like ChatGPT. This policy was dropped without advanced discussion or warning and without consideration of feedback from moderators or the many community policies against this content, including here.
We feel that this content is likely to mislead users, and if posted in bulk will overwhelm the quality control measures (human voters) we have here. ChatGPT-generated content tends to be elegantly confabulated, in the sense that it typically takes a lot of extra effort to evaluate despite being so often incorrect. Additionally, posting this content is dishonest and breaks standards of attribution. Users posting AI-generated answers are taking credit for content that they did not have a substantial role in creating and that they cannot vouch for.
All three moderators here are participating.
