What is Reddit's opinion of Notifications filter?

From 3.5 billion Reddit comments

A quick search found this app which I think may be useful. I'm going to give it a try. Hopefully this will rid me of those "Remember to watch" notifications... and you help you guys, too.

A long time ago I used Notifications filter, you can hide notifications from certain apps or create custom filters. And there are settings what to do with hidden stuff (e.g. It can display an icon when the hidden item appears)

The app is quite old, but give it a try, maybe it will be enough.
