X, the platform formerly known as Twitter, has started rolling out a controversial update to its block feature, allowing people you've blocked to see your public posts. The change, announced by owner Elon Musk in September, has sparked concerns over online harassment and raises questions about the platform's compliance with app store guidelines.

The update, which Musk claims promotes "greater transparency," has been met with criticism from users and experts, including Tracy Chou, founder of the anti-harassment tool Block Party. Chou argues that the change makes it easier for harassers to continue their behavior, highlighting the importance of "friction" in preventing online abuse.

The updated block feature also raises questions about X's compliance with app store guidelines. Both Apple and Google require social media apps to have robust blocking and reporting features in place to prevent harassment and abuse. It remains to be seen how X's new feature will be received by app store regulators and users alike.
