These ”mega donor” scandals happen near monthly as they are revealed via DTC autosomal DNA tests. It’s a combination of the unchecked power banks have to recruit and collect ad-nauseam sperm that sells very well. Donors may also go to other clinics where they are likely to be approved as well, but are not required to disclose their prior donor status. This results in an unmanageable number of sibling in these group. Also, ever since the industrial process of sperm and egg freezing, the accidental incest argument isn’t statistically significant anymore. It used to be that donors donated to clinics who then stored and did rounds of AI, IUI, or IVF depending on the needs of the client. Because these clinics were hyper local, donors were often in the same city or at least metro area as the DC offspring. Nowadays, gametes are shipped all over the US and the world so the likelihood of encountering a half sibling goes down significantly even for very large cohorts.
