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.
I guess this is why spamgourmet became almost unusable in recent years. It’s a pity because the service is effective at blocking spam but I can imagine there is abuse potential.
