The accusation of sexual misconduct at Brown is one of the things that worried us at CEA. But we approached Jacy primarily out of concern about other more recent reports from members of the animal advocacy and EA communities.
This feels like something that CEA could confirm or deny quite easily without damaging confidentiality or legal factors.
