Your intuition is borne out by the research into repeat undetected rapists, fwiw: https://yesmeansyesblog.wordpress.com/2009/11/12/meet-the-pr...

TL;DR, of the men asked a series of questions about sexual misbehavior that met legal definitions of attempted / completed rape but did not use the “r” word, 6-13% admitted to at least one offense, and 50% of those across both studies were repeat perpetrators with an average of 6 offenses each (and a median of 3, so there were some who were super-offenders).

The studies cited only looked at male perpetrators, an obvious limitation, but I think the work is really relevant nonetheless.

Surveying male funders, regarding their self-reported sexual behaviors and attitudes toward sexual expression, would be interesting as well. Are the same number of incidents reported by each gender? Why are men (mostly men) doing this? Have they experienced any feedback or consequences?

Not surprising, in long tail situations a small percentage end up having a huge effect on overall statistics.
