Did this account have a second factor? It's highly unusual for 2fa protected accounts to be compromised. And, proofs of possession usually come alongside the second factor: one time recovery codes.<p>Im just saying that the level of paranoia which leads to protonmail being the recovery mail address probably leads to it needing 2fa, and strong proofs of possession. Which should permit lower bar recovery of the account: if you can demonstrate its a false positive you can also demonstrate you are "you" in this context.<p>Admitting you broke the T&C suggests to me you might not want to armour up with accusations. You sure want protonmail to DTRT but you also have now conceded they can blow you off pretty much at will for breach of terms.<p>Totes sucks btw. I hope you regain. I also hope you have a backout plan to move account recovery mail while you still have control of other emails. Maybe hushmail? Or fast mail (I know, au crypto laws)
