A worse, more empty Tumblr. Sexual content was never the problem. It was Tumblr’s inability or unwillingness to invest the resources necessary, which every other social site has done, to eliminate illegal content, such as child pornography or revenge porn. This also doesn’t address the pornbot problem (again, something other sites have been able to address fairly successfully), nor will it address the false positive scrubbing of legitimate accounts. It also doesn’t address harassment of users. It further doesn’t address unprotected speech, such as hate speech or violence-enducing speech. Will this end tumblr? Only time will tell. But I can guarantee it won’t be the same and I get the feeling people will leave in droves.
