Seriously what is the point of these AI profiles?

Seems like everyone has noticed that some of the profiles on here are AI generated. Usually their profile pics are unrealistically glamorous and glossy; if you try to interact with them you soon find the answers make no sense. So these are extremely primitive programs; not only do they not meet the standards of a chatGPT, they are less convincing than your average customer service chatbot. So who is behind them and what is the point of them?
