This makes me 😭
UPDATE: Thanks @nekusoul@lemmy.nekusoul.de 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.
Just keep using the temp emails and when they don’t recieve your email , call them up. Their IT support will unblock it after 50-100 calls. Remember consumers have the power.
