what does add friend/add foe mean?

i haven't been on a forum in almost a decade, is this new or did the sonic fan forum i used to frequent just not have this?

I have no idea, I think it just adds them to your list.

Friends enable you quick access to members you communicate with frequently. If the template has relevant support any posts made by a friend may be highlighted.
Foes are users which will be ignored by default. Posts by these users will not be fully visible. Personal messages from foes are still permitted. Please note that you cannot ignore moderators or administrators.
