Some users[who?] posted the black square image using the hashtag #blacklivesmatter or #BLM (an acronym of the former), which in turn leads users who are searching those hashtags to find nothing but blank images. Some activists were concerned because the Black Lives Matter related hashtags are being used by activists and others to share information during the ongoing protests, and posting a black square with the incorrect hashtag risks drowning out critical information and updates.[11][12] Other users pointed to those participating in the Blackout Tuesday event, but not involving themselves in other forms of activism, such as protesting or donating, as being performative in their activism.[13]
