Colangelo has acknowledged having one of the accounts, which was inactive and reportedly used strictly for following players, agents, staff and the media to keep abreast of the news. He denied running the other four, calling the accusations "disturbing to [him] on many levels."
The evidence, however, tells a different story. A Ringer source noted that the patterns of follows, likes and tweets on each account were "extraordinarily similar." The site observed that the accounts followed people and institutions related to Colangelo and his family, and that three of the accounts conveniently went private within hours of calling the 76ers, which said they would ask Colangelo about the Twitter behavior. Others have observed that three out of the five accounts share the same last two phone number digits used for password resets, and that one of them was linked to Colangelo's personal email address.
The 76ers have since announced that they're investigating the allegations. If all the findings hold up, however, Colangelo is in serious trouble. Sports Illustrated's legal analyst believed that Colangelo might have been violating the collective bargaining agreements by publicly disclosing health info that was unrelated to their NBA careers. The allegations would have to go through the NBA's grievance resolution process, but could later lead to lawsuits over defamation and invasions of privacy.
Whatever the outcome, the report highlights just how complicated social media efforts can get in the modern era -- it's hard to be completely certain that a major persona is relying solely on their publicly known accounts. And if the revelations are true, they highlight how much effort is needed to cover your tracks. Colangelo might not have realized how relatively easy it would be for someone to establish connections between the accounts once word of them got out.
