The penalty for posting ChatGPT answers should be much, much harsher than 30 days.
Most of the people on SO are ........ computer programmers. It's remarkable that a coterie of computer programmers can be this "dumb" about ChatGPT.
ChatGPT knows literally nothing about - say - Swift and iOS. (Ask it almost anything to see this, say "How to convert degrees to radians in Swift." The answer is a mishmash of meaningless nonexistent calls, with perfect grammar and phrasing.)
A common problem on SO is, people who know nothing, posting grammatically correct and elegant answers, which are completely wrong, in a bizarre chase for points.
The only possible reason to post a ChatGPT answer on SO is such a bizarre chase for points.
Nothing is more annoying on SO than the "I'm trying to answer because I want to put in an answer" answers. Using a grammar-and-tone bot to paste answers in to SO is just madness. Anyone who does so should have the most draconian ban.
Just as, say, swearing on SO was easily eliminated by draconian bans, bot time-waste can very easily be eliminated on SO via draconian bans.
- There's just no room here for free publicity by some faux AI project, ban it out of existence.
