I've posted many furballing films, I've posted many one on one clips. However, if I go so far as arranging fights with someone privately, and for some reason wanted to post it, I would mention it to them. I consider it common courtesy, because it wasn't a random chance encounter, and they may not have been in the same mindset if it were "on the record". In fact they may have flown completely differently if they knew it would be thrown on the boards, as opposed to two friends bs'ing on private. Agree or disagree, understandable or bs, that's my take on it.
