I have been here for about 3-4 years, and have more than 80 friends, I have had trouble with some people and I have a neutral relationship with some people.
Despite having 80 friends, I can't remember a single name (since user names are fictitious and have been kept for their convenience) If ever we bumped into each other while visiting this site, we still remain strangers, only You can recognize your friends only on Friends Feed and Friends List.
This is also a reason that people are not socialized even when they are friends.
So I suggest that a big dot be displayed next to the user's name to identify them, based on the color of that dot, like a green dot for friends, a yellow dot for all users or strangers, and a red dot for the blocked users by you
just like the this picture
