i think it is easier to notice the posts generated through AI since the answer to some topics are somehow inconsistent to some extent so it is much easier to spot, also adding those overly excessive usage of grammars and too much flowery words.

Even before the creation of these GPT, there are posters that use excessive grammar and flowery words as they call, it will generalize these posters and they are being accused of something that they've been doing ever since long before these AI are created, you have to give them a benefit of a doubt and present a shred of strong evidence that these users are indeed users of AI
