On March 23rd, Blogger will no longer allow certain sexually explicit content

Infomation from google

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.

Changes you’ll see to your existing blogs

If your existing blog doesn’t have any sexually explicit or graphic nude images or video on it, you won’t notice any changes.
If your existing blog does have sexually explicit or graphic nude images or video, your blog will be made private after March 23, 2015. No content will be deleted, but private content can only be seen by the owner or admins of the blog and the people who the owner has shared the blog with.

Settings you can update for existing blogs

If your blog was created before March 23, 2015, and contains content that violates our new policy, you have a few options for changing your blog before the new policy starts:

• Remove sexually explicit or graphic nude images or video from your blog
• Mark your blog as private

If you’d rather take your blog down altogether, you can export your blog as a .xml file or archive your blog's text and images using Google Takeout.

Effect on new blogs

For any blogs created after March 23, 2015, we may remove the blog or take other action if it includes content that is sexually explicit or shows graphic nudity as explained in our content policy.
