Google has clarified it s policy on adult content for use on blogger from March 23, 2015. Existing blogs that violate the policy will require editing, or going private, or removing.

New blogs started after 23 March may get removed entirely, or other action may be taken, which I assume could mean reporting to the authorities.

Starting March 23, 2015, you won't be able to publicly share images and video that are sexually explicit or show graphic nudity on Blogger.

Note: We’ll still allow nudity if the content offers a substantial public benefit, for example in artistic, educational, documentary, or scientific contexts.Google Adult Content Policity on Blogger Changing March 23, 2015 [support.google.com]
