Tumblr porn ban goes into effect as huge numbers of posts disappear from site

Tumblr's ban on pornography is now in place, with a huge number of posts being wiped off the site entirely. Users will see their previously public posts disappear as the ban goes into effect. Many users have already indicated they are planning to leave the site because of the ban, and a movement known as the "log off" protest has tried to encourage even more. Tumblr announced the ban earlier this month. It was initially met with a vast backlash, by users who said it would penalise the substantial number of sex-positive, LGBT and sex worker communities that have unified around the site, which has traditionally been less conservative than other social networks.
