Facebook has decided to block user access to posts containing the viral #XX hashtag following the ongoing debate over gender eligibility in women’s Olympic boxing in Paris.

Users attempting to access posts featuring this hashtag have been met with a message, stating: “Keeping our community safe: Posts with #XX are temporarily hidden here. Some content in those posts goes against our community standards.” A “learn more” option subsequently redirects users to Facebook’s community standards policy.

The hashtag #XX – a reference to the female chromosomes – gained traction online following a symbolic gesture by two female Olympic boxers; their fingers shaped into an “X” following their match loss.
