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.
It appears that the Github user GalacticHypernova is not a contributor to the 7c/fakefilter project - just someone asking for some domains to be added. The current list does not contain proton.me or protonmail.com.
I suppose this might be a reasonable litmus test for the reliability of that list.
