I've manually blocked most official publishers. But I read plenty of stuff on Manga+ and like knowing when something is back from a break.
So I wish there was a way I could block chapters that are not newer from showing up in my feed. I like knowing there's a new chapter of Ruri Dragon up. I care not at all that they have chapters 1-4 of a series I've been reading for years. It seriously makes me consider blocking m+, even knowing that I'll probably miss some updates, so that I can see things that aren't effectively reuploads spammed en masse. Maybe someway that the system that groups individual chapters together can only show "New Chapter: It's a banger" (and 5 more) rather than 6 full lines.
