It’s a VPN rather than a proxy, but Windscribe is being considered to be added as a Privacy Guides recommended service. It’s also already recommended by Techlore (who are similarly strict with VPN recommendations) so I’d assume it’s compliant with Privacy Guides’ standards.
They offer static residential IPs which they advertise as having a reduced chance of blacklisting. I haven’t used it myself so I can’t speak to it’s effectiveness, but it’s the only service I’m aware of which seems to meet your criteria.
