The rec association that I played for and now coach for does NOT do background checks. It is a small community, where everyone knows everyone. We are not affiliated with any of the alphabet soup organizations. This is another reason we are not Pony affiliated (a lot of hassle, don't have a 12U or a 14U--cut it half with 13U which Pony wouldn't like, etc.). As one of those teenagers that helps out with the girls, I wouldn't think twice about letting a local, well known teen help out. Someone new to the area, someone I don't know... I'd do some investigating. Several of the parents who played fall ball for me didn't know me at all. I had some girls on the team that I had never met before. I was the head coach, no one else would do it, the girls wanted a team, I was available and I love it, so everyone won! Several of the parents that did not know me admitted to calling around and asking about me before committing their child to my team. Needless to say, I came up clean.
