Yesterday Tumbler enacted a permanent ban on adult content. This is just the latest in a series of announcements that have gradually downgraded content on their platform that is intended for adults only. Banned content includes photos, videos, and GIFs of human genitalia, female-presenting nipples, and any media involving sex acts, including illustrations. Tumblr is not alone in the war against adult content creators and sex workers. Tumblr was particularly harmful to the adult content crowd because when it was founded they were one of the few social media platforms that fully allowed adult content. Like many other apps and services, they allowed adult content to grow their base and then abandoned them, later on, to chase after general audience advertisers.
