However I want to redirect these websites to another website I have online informing the user this is blocked content

Answer 1

You cannot redirect to a website per se – the only think you can try is to get the ip address the website is hosted on and if the server is set to handle the request, it will work. That means it’s not going to work on shared servers that has one IP.

For more sophisticated redirect, you have to use other solution.
