How Accurate Is ProxyCheck for Detecting Proxies and VPNs? or Does ProxyCheck Really Block All Proxy

Proxycheck is decent, but if you’re serious about blocking *all* proxies, you gotta layer it.

Cloudflare’s firewall rules + proxycheck works like a charm for me.

Also, yeah, the lag is real on high-traffic sites. Tweaked the cache settings and it helped a bit.
