Blacklist

Hi,

Just wondering how do I use the Blacklist.Add function?

Code:

List<TorNpc> Objects = ObjectManager.GetObjects<TorNpc>().Where(o => o.Distance < 1.0f).ToList();

I assume I can call Blacklist function on each of the objects I interact with, so they won't come again next check, but not sure how to use it. If someone can help?
