Best VPNs right now:

Mullvad: good performance, anonymous payment, no email account

Obscura VPN: can't be blocked by VPN detectors, anonymous payment, no email account, but only Mac client for now (will change in near future)

NymVPN: zero-knowledge network, anonymous payments, no email account, covers & obfuscates traffic, but no wireguard configs for routers yet

What I don't count:

ProtonVPN: no anonymous payments => KYC

LNVPN: Lightning payments but has data transfer limits
