I previously commented I would write the support, now I actually read the docs first and found out why:

If you want to create an account over tor you can, just not via the clearnet URL, probably due to rate limiting by IP adress. However if you use their Onion Link as specified in this article by their support (https://proton.me/support/tor-setup) it works just fine (as far as I just tested). So great! Because using .onion services is far more secure than accessing clearnet over Tor anyway.

Here the url, verify it with the link in the support article tho: https://protonmailrmez3lotccipshtkleegetolb73fuirgj7r4o4vfu7ozyd.onion/

Have you actually asked proton support about this issue, if so what have they said?

It seems like you got frustrated and instead of trying to get help you decided to complain on lemmy.

Just tested it, same here. Clearnet works but tor not. I will contact support since part of the reason I like to pay for unlimited is to subsidize free, anonymous accounts.

Edit: here is my other comment:

What makes you think this has anything to do with Tor?

Does anybody know valid alternatives to proton mail, I think they have been enshitified

While on dread recently I stumbled across this old post regarding issues with their onion adresses https://encryp.ch/blog/disturbing-facts-about-protonmail/

When a user makes a new account with Protonmail on TOR they are re-directed from Protonmail’s “.onion” to “.com” address. This breaks your secure encrypted connection to their onion address, enabling your identification. There are absolutely no technical reasons for this feature. In fact, the only other websites that operate like this are suspected NSA/CIA Honeypots.

Change your route, people using tor with the same exit as you are doing too many username checks.

yup, i keep saying it.
