Redirect user if using proxy or vpn services web - .htaccess

Question

I need advice how can I redirect user to my "custom.html" page and inform them that they are using vpn service or proxies.
I wish my code work just like this site: https://awebanalysis.com/en/ip-proxy-checker/
Screen detection shows that I use VPN]: https://i.stack.imgur.com/5Fvv4.png
I'mdoing this because there is a live chat in my website and I can ban only IP and there is a guy who come to my site every day few times with different IP from different VPNs and insulting me and makes jokes. So if he will come with real IP since he wont be able to load my index.html if using proxies or vpn I will caught his IP.
I added this code to my .htaccess file but it allow me to vist if Im under vpn or proxies.
