Keiran is fairly ubiquitous but I don't consider him annoying. I don't mind him in the slightest. If I see him or Sins or Danny, I know the scene's going to be good. Although I'm hard pressed to think of many current performers that actively annoy me.... there are a few that while that have big members and can fuck for days, their money shot is always a weak dribble with hardly any force and a very small amount of jizz, and that always disappoints me, but I can't remember any of their names.
There was a guy in the 90s/early C21st scene that seemed to have no respect for the female talent and routinely used to shout "Fuck you!" when he was spaffing on their faces, I hated him. I have it committed to memory when he did it to Briana Banks, because I really loved her, and it made me want to stab him.
