One of the problems, as far as I can tell, is that the clubs nor rinks are liable for the coaches' behavior since they're, generally, independent contractors. The easiest solution, for the rink and club management is to run a bad coach out of town and not deal with the authorities, and thus open themselves up to any legal culpability for what took place at their rink or happened to their club members.
One of the most high profile cases besides Callaghan from 20ish years ago involved Bob Young, who was actually employed by two different rinks in the Hartford, CT, area.
Young was executive director of the ISCC in Simsbury and was involved with bringing in a lot of the Russian and Ukrainian skaters who moved there after ‘94. There were very brief mentions in the media in February of 2000 that he had been accused of sexual harassment by one of his former students.
A Hartford Courant article from 5/25/2000 (paywalled; unfortunately I don’t have a way to post a link) reported that he had recently stepped down as executive director at the ISCC and was hired as executive director at a facility in Newington later that same month. The article notes that the owner of the new rink was not concerned about “allegations of sexual harassment” that, per the Simsbury police, were still under investigation at that time.
Per U.S. Figure Skating’s website, Young’s lifetime ban became effective in July 2002. Two different articles from the Hartford Courant on 1/17 and 1/19/03 reference him as coaching a top junior pairs team at the facility in Newington,
after that lifetime ban went into effect. (There’s no reference to whether he was still an official employee of the rink, though.) He would not have been issued coaching credentials for competitions after the ban, but based on an archived version of the USFSA website from December of 2002, he
was still listed as coach in that pair’s national team bio.
Two more skaters went public with accusations in 2007. (It was reported a month later that police dropped their investigation into one of those cases because they couldn’t establish whether the statute of limitations had expired based on the timeline.)
A former world-class figure skating coach who was banned from national competitions after settling a sexual abuse lawsuit faces new allegations of abusing skaters.

All of this was a matter of public record and Young was still coaching at the elite level for years after the original story broke in the media. While some things have changed since then, I still think there’s a lot about this story that illustrates some of the ways the culture of skating tends to protect people who are powerful and well-connected against accusations of wrongdoing.
