I offer a freemium service to my clients. To make sure that nobody is abusing the "free" part I added mobile phone verification.
But I also want to make everything as smooth as possible to administrate - ban tor, well known VPN providers, proxies etc from accessing my site.
I would use the nginx geoIp module, but how do I get a list of constantly updated IPs? Are there any services that would provide this? It doesn't have to be free.
Thanks
