So I finally found a way to scrape SubscribeStar, it's Alessandro-Gobbetti/IR (
https://github.com/Alessandro-Gobbetti/IR ) (It's a web scrapping app built on MERN stack). To run it, you will have to download the code to your computer, open it in vscode and run the backend and frontend server using the terminal.
Any tech-geeks here willing to run it in a browser?
