The purpose of all stock market manipulators is to make profits, to make money. Some of them spread the news artificially, and some used the news to let retail investors take over. They are easy to realize. The essence of issuing stocks is that companies have to give up their owners' equity to attract social investment because of insufficient capital. If you can't buy stocks, it is a financing failure. If you want to sell it, someone must manipulate it and act in concert to achieve the lowest capital cost.
Some news may affect investors and manipulators to use and amplify these news to achieve their goals.
