Use of ChatGPT generated text for posts on Stack Overflow is temporarily banned.
However, the reasons for the ban really apply to much or all of the network, and certainly for sites that are similar in nature to Stack Overflow.
I suggest (temporarily) banning ChatGPT network-wide.
It turns out that ChatGPT can give correct (or correct-looking) answers even for subjects of sites that are not at all like Stack Overflow. I asked an unanswered question from Judaism.SE and got a fairly good answer.
