Have attempted other permutations such as older variants /blist add "player name" and get the same error.
It's esoteric and stupid. In order to blist someone, the person you're trying to blist has to be online. You also can't have them on your friend's list. But if you remove them from your friend's list, it DOES NOT automatically remove you from their friend's list. Meaning you'll show up whenever you go online, along with whatever color changes for friends.

At the very least, when you search their name, you can right click and blist them there. But again, they have to be online in order for your to blist them.

The only other option is if you've done anything with them, aka in contacts for dungeons and etc.
