It is pretty funny because what Tumblr is now missing is high quality edgy stuff, including content curated by photographers while bot-generated/resposted porn shows up again as fast as Tumblr's systems kill it.
Tfa mentions at least 7000 dick pics, and the 'fitness' tag. So yeah, the purge was awful from both ends. I can only imangine the users feel like they are inhabiting some sort of wasteland when they go beyond their feeds.
