I think that K should be about posts, not about people. Both ways.
Having a list of people you hit for green every day regardless of what they post? I wish there were a way to make that bannable. My opinion, not site policy. George and I don't always see eye to eye. But when someone mentions having that list, don't think I don't notice or that I don't care.
Bombing someone just because you got crossed up with them three months ago or whatever, that's also a bad idea. Keeps you from learning valuable lessons. Either way, you don't know the person, you only know what they post.
