ProtonMail addresses blocked

Hello,

I am Goran from ProtonMail's Customer Support team.

We've received complaints from our users they are unable
to sign up to Mojang with a protonmail.com address.

 

We would like to work with you on resolving this conflict between our services. If this is an intentional block of ProtonMail addresses, it would help us to know what triggered it. Could you please provide us with more information? What kind of activity from ProtonMail users determined Mojang's policy to block ProtonMail addresses?

Our anti-abuse team is constantly working on solving these issues with the aim to protect companies such as Mojang and would greatly appreciate any feedback at antiabuse@protonmail.com.

If you are not the right person to contact on this matter, I would be very grateful if you could direct me to someone who can help us resolve this issue.

Best regards,
Goran
