The social media initiative, aimed at muting self-promotional and commercial content in favor of amplifying black voices, involves supporters of Black Lives Matter posting a black square on their Instagram account, followed by information concerning police brutality, community updates, and the like.

The “Little Women” actress, 30, opted to post three black squares, each with hashtags — Blackout Tuesday, The Show Must Be Paused, Amplify Melanated Voices, and Amplify Black voices — attached.

But Watson was soon accused of performative activism, with users pointing out that the black squares she posted were edited to match the aesthetic of her Instagram account. Others noted that the “Harry Potter” star hadn’t said a word about the death of George Floyd or racial tensions in general until #BlackoutTuesday.

“The way emma watson touts herself as an activist and has said nothing but three blank squares on instagram tells you how much of a white feminist she is,” wrote one critic, while another added, “did emma watson rly put a damn border on her blackout tuesday post so it would fit her aesthetic… f–k that… and f–k the fact that this is the only time she’s spoken up and it literally contributes NOTHING… miss me with that white feminist bs.” 

Many celebs and brands have participated in #BlackoutTuesday, including Rihanna, Reese Witherspoon and Alex Rodriguez.
