Or when posting using AI the post shouldn't be allowed, like the Forum should have an inbuilt AI detector that won't allow the user to drop the post and it should be having a red sign that the post is an AI post.
It's not so easy. Let's see on this user Adams0001. Usually he makes some edits to the texts so detectors don't easily catch him. You can probably catch him manually, but it will take lots of time. If you'll read his texts you'll see that some of them are kind of technical, people don't speak that way usually. So as human beings we can see that it is not natural. But AI detectors sometimes don't see the same.
But he made at least one big mistake:
Cryptocurrency has grown in popularity in recent years as a means of doing transactions that are faster, cheaper, and more secure than traditional methods. However, cryptocurrency's future is uncertain, and it is possible that it will not last forever. One of the most significant difficulties for bitcoin is regulatory ambiguity. Many governments around the world are still attempting to figure out how to regulate bitcoin. This has resulted in a lack of clarity and consistency in the regulatory framework, which can lead to market uncertainty and volatility. This, in turn, may make it difficult for businesses and individuals to use cryptocurrencies, limiting its acceptance and threatening its long-term survival.
This post is easily detected by each detector with 99%+. Moreover we can check it with a plagiarism tool like text.ru and see results which are characterful for AI written: big parts taken from some other texts sometimes with whole phrases.
So now we are sure he is using AI, but how can a detector know it about some other texts with automated results of 0% probability?
I tried to get three posts of him for AI Spam Report Reference Thread, but changes he makes (sometimes he just deletes some parts of text) make it harder. Some texts have 60%+ of AI probability, some have 50%+, and I'm not motivated to spend too much time on him. So automated detectors failed.
If a user, let's take the case of this Adams0001 if he keeps editing without being found as an AI user, can't it be seen as someone who's not using AI because of the editing?
Since the tool you're using failed to detect his post while using AI, are there no other means to find him guilty of using AI?
