How do I stop getting updates on re-released chapters?

[Sidhe]

When I go to "Follows" is there any way to not see chapters that already have a release?

example: reading 'Marimashita! Iruma kun' and scan group misfits decided to start scanlating it from chapter 1 again and now I'm getting notifications/updates to read chapter 4, when I've already read that chapter- even if it was by someone else.

I see I could try blocking the group that's doing that, but they also release other stuff that isn't a re-release so i'd miss out on all that.

Would be nice, but the problem there is what happens if someone "trolls" by releasing crappy speed scanlations before the real quality comes out?

You are pretty much out of luck on this one, admittedly. At least it is pretty easy to spot certain new uploads if you are reading the Follows list carefully, and you can go ahead and just mark the new ones as read from there without going to the manga or even reading them. Sometimes, it may be worth the time to check out the newer update as it may have been done much better than the previous upload(s).
