The World Favorites tab in the Website provides a feature that lets users to select multiple worlds and execute Delete or Move actions, but this feature does not work properly. For example, if I select over 30 worlds and try Delete favorites, the progress bar often stops halfway through, and the process does not complete. Looking at the status code, it returns a 429 (Too Many Requests) error. It seems the script is sending a delete request for each individual Favorite World, so I suspect this is due to an inappropriate interval or simply because the current implementation is not designed efficiently.
