2010s Black Tumblr didn’t die organically. It was killed. Not just by staff, not just by the porn ban, but by the white userbase as well. Black bloggers were (and still are) being mass-reported and harassed off the platform constantly. White Tumblr users would post gore in problack tags, racefake left and right in Black people’s askbox, pick random AAVE to call racist/misogynistic/transphobic, etc then get the Black people who were nice enough to explain what it means to them mass reported for harassment, the list goes on.
