Susan rocks! I don't know her personally, but have read many a post by her and corresponded with her via email.  She's a smart cookie who cares a lot about others.

Runners, ultrarunners, trail runners, race directors etc. are people.  Some are nice; some are not.  Believing that a person is a decent human being because they can run is mistake.  I think she has the right idea about being more selective.  

The nice folks will receive their rewards.  The icky ones... well, they can go on living their unhappy lives.  

  What's your point? What means "bad ultrarunners?" For every 20 people regardless of reason for gathering, there will be at least one eccentric person. I will contend that road races have more of those eccentric people than trail races and even less in ultra trail races. The longer the race the more at peace people are with themselves. The few A-holes that ooze through, ignore.

 When I read this I think the difference is the size and intimacy of the event.  A-holes are never welcome but when 12 ppl out of 89 are fussing it can be a lot.  She points to the sense of community and I interpret that she is upset at these folks disrupting the sense of community that exists with these ultrarunners
