Reasoning

Per REPORTED_ALLEGATION RULE and DENIAL/REBUTTAL RULE, scoring the underlying allegation: Dershowitz allegedly had sex with an unidentified woman at Epstein's parties. Epstein's characterization as 'fantasy' does not lower the score. Allegations of sexual activity with unnamed individuals at Epstein-controlled parties constitute exploitation-related misconduct. High confidence due to specificity of sexual allegation, though not maximum due to Epstein's denial.
