Across 3 VPN providers I use, none of them have issues accessing reddit anonymously. There are nodes/regions that are blocked, but finding a working server isn't hard.

Might be you're logged in? I often hit a block when using (proton) vpn if I'm logged out but not otherwise.

Indeed - sloppy reading on my part.

Care to name them? I use Mullvad, and I love them, but their exit nodes are routinely blocked by Reddit and streaming services.

Mostly VPNs that don't show their infrastructure publicly (or at least their IP pools) seem to be working across Reddit.

Of the largest providers[1], PIA and nordvpn work fine for me.
