That’s not my experience, using various VPNs, public networks, Cloudflare and Apple private relays. A captcha is common when logged out but that’s about it, I have not encountered any shadow bans. I create a new account each week.

That's not the same as "blocks all data to non-residential IP's"?

See my other comment. I agree there's a non-zero amount of VPNs that are banned from reddit, but it's also not particularly hard to find a VPN that's not banned on reddit.
