This seems to happens since the due date popup was updated to include a reminder, just a few days ago: I change a due date or add one and the follow is activated. Above all, I do not want these reminders (nor the badge icons on iOS), unless I explicitly follow a card or add myself to it. This worked perfectly fine up to now, but the changed behaviour is not what I want. At all. I hope this is a bug and not a feature.
