I remember a discussion where people were so sure in their ability to detect AI, when SE decided to not allow dealing with potential ChatGPT answers.
What I see in reality, occassionally, is that most people have 0 clue on how to detect AI, apart from the most obvious cases that are 90-100% copy pastes from ChatGPT. Here are some recent cases of nonsensical accusations:
- my longer answer about captchas (accusation got reported and deleted, but downvote and delete vote stayed as of now).
The only suspicious things here are paragraph splits and decent enough English - but it's definitely not even perfect. Otherwise, a lot of phrases and wording are what AI would never use - "1st", "(= ...)", "have/want", etc. There's also some doubt/uncertainty which AI very rarely shows.
Any popular AI detectors gave this 0% rating, so no clue where the idea came from. These tools aren't perfect either ofc, but if they show no relation to AI at all, I don't know what's the point of trying to accuse someone. In that case AI usage is hidden so well that the idea is copied but the post is fully rewritten, which can't ever be proven. Even if contents are incorrect, as the poster could just be wrong himself.
- this answer about ffmpeg and Opus format.
Similarly, it's longer, it has paragraphs, good English and... that's it. It has even more syntaxes and wording that AIs wouldn't go for - unclosed (, "file/stream", quoted frames, "(1)" type of refences in the middle of text, etc. The ratings are yet again 0. No idea what encouraged someone to instantly write a comment about ChatGPT.
The fact that comments can contain basically anything and are only up for mods to remove if you report them doesn't help here. IMO bad comments should be more punishable, but that's another topic.
I'll just end this with a note that you don't just go to a store and accuse people of selling fakes with 0 analysis of the products. That's complete lack of manners and common sense and could actually lead to your arrest and a court case against you for defamation or anything similar. You also can't pick some random books in local library and damage them because you think they're copied. Internet is more free in terms of speech, but shouldn't be more free in terms of vandalism - yes, I think that attempting to discourage good quality answers in a mindless way is exactly that. Think about it.
