the age gaps, where imo the older skaters are not mature or responsible like actual adults and therefore create situations like this,
This is an important point that I think all rinks need to take seriously, not just those associated with USFSA. In youth sports, and maybe especially "early peaking" sports like figure skating and gymnastics where athletes are grouped by ability, not just age, and where practice sessions are mixed-age, there
is a lot of mixing of age groups and a sort of false peer-hood among skaters of wildly differing ages and maturity levels.
And in cases where older teen/young adult skaters may also be coaches, there is a lot of grey area when it comes to peer-mentor-authority that lends itself to both mixed messages and openings for grooming behaviors and potential abuse.
I think this is an area where ISI, USFSA, USA Hockey and rink associations need to get on the same page with a clear, unified message to skaters, coaches and parents.
I know I've had this conversation with my daughter as she moves into coaching; that it would be prudent and proper to make sure all her interactions with younger skaters are kept professional and with her in the role of adult, as much as she might like to be "buddy buddy" with some of the students/younger friends while she's practicing on freestyle or hanging out in the lobby, etc. This is for the safety of younger children, especially those who might thrive on being favorites of a coach -- parents need to be able to recognize right away when a coach/older skater - younger skater relationship is not "right"; normalizing those grey area relationships at the rink does not help anyone and I'm not sure enough coaches are educated in maintaining appropriate boundaries.
Again, definitely not saying that coaches who are buddy-buddy with kids or who play favorites are necessarily grooming, but when there is a defined and repeated ethical expectation that all coach/student relationships are more clearly professional-only, I think it can help keep kids safe and could more clearly reveal unsafe relationships.
