From Fanlore:
“Others pointed out that Tumblr’s implementation was chaotic and lacked human review. For example, fan art that depicted robots having sex with tentacle monsters was deleted for bestiality, which led one fan to mourn that even Hollywood Oscar award winning movies were at risk:
“I guess this means The Shape of Water is a no-no as well? /stares mournfully at gifs of fishloving" [25]
When the artist attempted to explain to Tumblr that the “characters” were cartoon dinosaur robots, they were told: “"This termination is final, and replies to this message will not be reviewed.” [26]
Complicating matters was Tumblr’s shadow ban of certain keyword searches that could have assisted in ascertaining the extent of the impact: searches for “tumblr purge” led to no results. [27] Other banned searches included “fandom wank” possibly due to one of the words also having sexual connotation in the UK. The list of search terms blanked included: “"breast cancer,” “safe sex” and “chronic pain”.[28]
Perhaps one fan summed it up best:
“Tumblr dies the way it lived: completely fucking ridiculous.
If you have more info – please add to the Fanlore page! If you’re shy about editing, add notes to the Talk page, and someone can fold in the details to the main page later.
I’m starting to believe that even if Tumblr remains somewhat functional for some of us, we’re reaching a point where we have some degree of ethical responsibility to leave and encourage others to leave, or at least refrain from making this a primary social network.
A site that conceals medical information from its users is not a good or healthy place to be.
