In 2021, the Fellowship revealed that Elio Qoshi is the Ubuntu employee and Mozilla Tech Speaker who recruited an underage girlfriend while he was Fedora Ambassador.
Search results show his profile was included in the FOSDEM 2022 program but if we click the link, it doesn't go anywhere, he has been removed.
In many countries there are laws obliging people to inform the police about known cases of child abuse. If the people who removed Qoshi from the program know something about the abuse or if details have been shared on private mailing lists then anybody who has received that information may be under an obligation to report it.
Open source contributors who are employed in universities, schools, health care or law enforcement organizations may have additional obligations to report any information about these relationships.
