Reddit too, I wished they offered residential or dedicated and/or unlisted ips. But most of the time you just have to cycle through different ips to unblock.

At this point in the cat/mouse game, wouldn't any set of IPs used by a VPN eventually be able to be sussed out by anyone interested?

Some vpn services offer dedicated residential IP addresses, meaning you get an IP from just a regular private ISP in some other country. It's admittedly a bit shady though, and more expensive ofc but that will unblock everything

There was a bumpy ride with CF a while ago but they seem fine now (still plenty of captchas, of course)
