After Elexus Jionde’s 9/11 tweet went viral, a potential Twitter bug disabled threading on the tweetstorm it was meant to introduce, removing crucial context and exposing her to further abuse.

On Sunday evening, the 15th anniversary of the September 11th attacks, Elexus Jionde, a 22-year-old history graduate from Charlotte, North Carolina, tweeted:

When the tweet went viral (50,000 retweets in less than 24 hours), Jionde decided to add to it, detailing key parts of black history in the US. Her goal was to highlight periods of racism and injustice that she believed should be remembered in the same way as 9/11. To give the tweetstorm continuity — and to make her tweets easily discoverable — Jionde threaded them together by replying to each tweet as she published it. (You'll find the full thread — which is made up of 49 tweets detailing many other examples of racial inequality in US history, and asking for them to “not be forgotten” — here).
