Interesting topic, but the way the poll question is phrased, I doubt you'll get what you're looing for. In fact, I am not sure what you're looking for.
I voted that I "call" all of them, based upon the fact that I've played a lot of tournaments and when I've recognized something and handled it properly on my end I've called it. I have never in actuality called a practice throw, likely because by the time I understood that rule I was playing in a division where guys have never done that.
I've never called a player for not marking/flipping the disc, because a little preventive officiating keeps that from ever happening. I always have 5 or 6 marker discs on me. So I voted I would "call" it, and I would if the player was told by me that he needed to mark his disc, I offered him to borrow one of my markers, etc etc, and he then basically did what he wanted to anyway. But I don't see that ever happening. But I voted on the pool that I'd call it for that reason.
When a guy cusses up a storm and has an overall never-ending bad attitude and actions, I'll call that courtesy violation. Or if a player is unofficially warned by me about something and how to do it right, and still continuously violates the rule, I'll call that courtesy violation. It has happened once in many years. And I call blatant violations of the rules, foot faults, etc., particularly after I've done at least one attempt at preventive officiating.
