In a controversial move Monday, Twitter suspended the account operated by Virginia Tech University swimmer Reka Gyorgy, who only hours earlier had called for fans and fellow swimmers to boycott future competitions over the NCAA’s decision to allow transgender University of Pennsylvania swimmer Lia Thomas to compete.

The suspension followed a tweet issued by Gyogry on Sunday in which the decorated collegiate swimmer complained that her slot in the NCAA finals had been “stolen” from her by Thomas, whom she accurately described as a “biological male.”

“My finals spot was stolen by Lia Thomas, who is a biological male,” Gyorgy wrote, adding, “Until we all refuse to compete nothing will change. Thanks for all the support retweets and follows I won’t stop fighting.”

As of early Monday afternoon, Gyorgy’s account had been suspended.
