The accounts also took aim at former Sixers general manager Sam Hinkie, Toronto Raptors executive Masai Ujiri and former Sixers players Jahlil Okafor and Nerlens Noel, according to a report by The Ringer.
In response, the 76ers issued a statement Wednesday morning:
An online media outlet filed a story linking multiple social media accounts to 76ers President of Basketball Operations Bryan Colangelo. The allegations are serious and we have commenced an independent investigation into the matter. We will report the results of that investigation as soon as it is concluded.

The website asked the team about five Twitter accounts it suspected Colangelo was operating. He said in a statement he used one of the accounts to monitor the NBA industry and other current events, but he was "not familiar with any of the other accounts" brought to his attention and he didn't know who was "behind them or what their motives may be in using them."
Embiid told ESPN on Tuesday night that Colangelo called him and denied the article.
Sixers All-Star center Joel Embiid tells ESPN on Bryan Colangelo: “I talked to him and he said that he didn’t say that. He called me just to deny the story. Gotta believe him until proven otherwise. If true though, that would be really bad.”— Adrian Wojnarowski (@wojespn) May 30, 2018
The 24-year-old center also tweeted that he didn't believe the story.
"That would just be insane," he wrote.
Yahoo Sports reported Colangelo was standing by his statement to The Ringer.
Colangelo was hired as president of basketball operations for Philadelphia in April 2016. He also served as Toronto's general manager from 2006-2013.
Colangelo, the son of longtime sports executive Jerry Colangelo, stepped in with the Sixers after Hinkie resigned. He lost his GM job in Toronto after the Raptors missed the playoffs for the fifth consecutive season, and Ujiri took over basketball operations.
According to The Ringer, one of the Twitter accounts it connected to Colangelo downplayed Hinkie's role in the franchise's turnaround. It also lamented in another post that Ujiri hadn't done anything to make the Raptors better.
Another account accused Embiid of "playing like a toddler having tantrums," and one criticized Fultz for his work with his "so called mentor/father figure."
Houston Rockets GM Daryl Morey had some fun with the story on creating ways to confirm someone is not using a fake account.
"You need two blue checks to confirm you are not a burner," he wrote on Twitter, referring to the blue verified check on the social media platform.
