How does 4chan index vpn addresses?anondfd112
08/11/2019 (Sun) 17:10:531217Mod
I use openvpn and get free ones from vpngate, only pick ones with under 1000 sessions in the past. In about 10% of cases I get by 4chan's vpn filter. Do they just gather data from open sites like that periodically? Also, does someone know how to get vpngate or an alternative to show me only rarely used vpns.

vpngate ips are public

I assume they have some kind of bot that scraps ip addresses from popular proxy sites and then adds them into a big ban list.

There are blocklists for anonymization services (proxies, VPNs, Tor). E.g. this one has 990527 subnets and 1027266 IPs.
