Centralized exchanges only think about the commission income they will earn. If there is a high-volume shit token, they don't hesitate to list it right away. Please see the latest memecoins listed by Binance. Apart from that, if you pay them certain fees, they can list you. There are many accusations leveled against Binance in this regard. I always gave bad examples about Binance, but my purpose is not to defame Binance. Binance is the best centralized exchange in this market, but even Binance does it. I don't want to get into a topic about what we should think about the rest.
