I tried Yandex but I think since I'm using Tor they limited my account and asked for SMS. ProtonMail required email confirmation from another email so it's rather chicken and egg. Some systems work on an invite principle so that could work, or maybe to request an account with an appeal in text. Finally, if spam is the issue paying with some crypto might be possible.
VCs are just there to protect the CC companies. They don't care about your data. Even the term identity theft is a scam. It's not your identity you protect, but their money. The way to protect your identity and information is not to give it out in the first place.
This isn't what happened for me. They wanted an email confirmation so it's rather chicken and egg. Maybe tutanota will work as an initial provider then i can get a protonmail. It seems these services have their ideas about which are acceptable for what.
