Yeah, trying to blacklist everything you don’t like seems like an endless game of whack-a-mole. Easier to just whitelist what you want.
EDIT: Another reason to subscribe is that you will only see traffic from a remote community on All if at least one person on your home instance has subscribed to it. So if you just browse All, you may never see some stuff at all, and if all the people subscribed to a community unsubscribe and the community isn’t on your home instance, you’ll stop seeing new material from it. If you subscribe, then it’ll show up and keep showing up.
You don’t want the “/c/” prefix – take that off and it’ll produce a home-instance-agnostic hyperlink automatically for people reading the comment.
