The problem with this kind of thing is I can add all the people listed here to circle I will call HN, but the people who get added by me will have no idea who the hell I am. They would have to check this list to verify if the guy adding them is from HN or not...
This problem should alleviate itself. If you add everyone in the list and someone adds you, and you hover on their profile and see that you have 5, or 10, or 15 mutual connections (usually with foreign names), you can infer that it must be someone from HN that's adding you.
