I think Kominfo just went full retard lately. They block anything that contain p0rn even if that only small part. Few days ago I heard tumblr is going to be blocked. I’m not active there and I think their community isn’t that great but AFAIK their p0rn content is small compared to dedicated p0rn site. Most of it it just user generated content thus tumblr almost has no authority.
Here is pictures unrelated with the topic.
