This makes me 😭
UPDATE: Thanks @[email protected] for this update: The issue has now been commented on and was closed by the maintainer, where they explained why those blocks would be nonsense. But it appears the OP wants to still talk with maintainer privately about it.
Do keep in mind, it seems like protonmail is considered a whitelisted domain in the eyes of lead that’s running that project. I say this because if you go under the issues page of it and then select the whitelist issue which is the issue that he uses to keep track of every domain that will not be blacklisted, protonmail appears there. That being said the others don’t appear.
