It may work anywhere on internet where anyone could pass a AI generated text to get a payment.
There is a market for people to write essays and reports on internet and I am afraid universities and teachers still do not have reliable tools to tell the difference.
The difference can be spotted, only when there is a person who is either not fluent in English or not a native. However, a person with good English skills can easily surpass the AI detector test by making some changes to the text (I saw one example in this thread only) and some twisting here and there with a precis or word cuts cannot let even AI decide whether a person wrote the stuff or got it from AI.
But, in the cases of essay writing and report writing given to students by their professors, where the TL;DR applies to some lazy students, they won't change anything or even if they do and are not so fluent or know native English of the specific country (for example, there are differences in some words of UK and US English and even more), the professors will be able to easily catch those students and suspend them.
And, congratulations to Royse and Loyce for finding one user in one of Royse's campaigns. This will give a lesson to AI users that we are ahead of any technology because we created these things.
